T0ETSR3-- DATE: JULY - 1935 INTRODUCTION: Production on this toner pulp continued, high, a total of five hatches being made during the month. This color has been turned over to plant supervision and all but the first of these batches were made without supervision by the Development Section. Reworking, mixing and testing of all the pulps, however, is still under Development/and. Re search supervision. Also included in this report are three batches outstanding from last month. SUMMARY & CONCLUSIONS: The three batches outstanding since last month were all made using the CS-7904 formulation. Two of these batches, 44371 and 44402 have been accepted by the Paper Laboratory and have been shipped to partially fill an order for 5,000 lbs, of pulp. The other batch, 44332, was rejected by the Paper Laboratory and has been transferred to standard stock as Q.K. for rubber. The first two batches made during July were made on the CS-7904 formulation. The first batch, 44426, was made under the supervision of the Development Section, while the second, 44482, was made under plant supervision. Both of these batches were accepted bythe Paper Laboratory and have been shipped to Philadelphia Dyestuffs Sales, One more batch is needed to complete a recent order for GT-68-P for paper. The last three batches made during the month were made under plant supervision checking the 41873 formulation. The first two of these, 44521 and 44547 have been rejected by the Paper Laboratory, being very weak and dirty; the other one 44581, is still awaiting paper test. Rubber tests on these last three batehesfere also in process. Yields on the four batches made under..1 development supervision, including the three batches outstanding from last month,were uniformly satisfactory, averaging 97$ of estimate wbieh is 1$ better then previous production. The four batches made under plant supervision were uniformly low in yield, averaging 91$ of estimate or 5$ under average production. The first of the plant supervised batches (44482) was higher in dry content than usual (29,5$) which may have been due to the use of the pump when pressing or washing. It was necessary to add water to this batch when re-working in order to secure a pulp of standard dry con tent (27$), Production and shipments for the month of July are tabulated in Tables I and II respectively.

SUMMARY & CCNCLUSiQHa: Some further study has been carried out on the preparation of the specially treated Victorla Blue B B.T.A* foilowing the method used in preparing the base for Blue YD (Bye 92$*) a greener and cleaner lake is obtained than that obtained by the method previously used.

In view of the faot that this latter group includes such well known dispersing agents as the tri ethanolamine and sodium soaps of stearic and oleic acids, the wisdom of any further consideration of a patent application ia extremely doubtful. Vo are, therefore, recommending that no application be filed. A number of mixes were made in selecting a match for RL-400-D to fill an order for B*F.

Si^JU^^AjC (2j^ & IETRODUCTIQH: ^ v 2-' FlLBiFgMv EBB - & DATE: JULY - 19S5 Work was continued in July pn the preparation of this Lithosol Red 2-B toner in. the Semi-Works using a new shipment of dye, lot 3 fran the Dye Works, five batches were made varying the formula slightly in an attempt to secure desk masstone material. Three large batches of the extended toner were also made to build up a stock of this eolor preparatory to setting up a standard. BTTMMSHY ft CONCLPSI OHS: The first batch was made to check the CS-7853 fomulati on- using lot 3 of the dye. The resultant toner was brighter, v.v.s stronger and v.s. yellower than CS-7853, > '}fi Dissolving the calcium and strontium chlorides in a gmeji ^ amount of water and dumping in instead of striking in 10 minutes gave lighter and v.s, yellower results than the regular CS-7853 formulation. _ Striking at 60 ? instead of 75 F also gave lighter and V.s. yellower results, 1 A hatch made to cheek the second bateh (fast strike) gave practically check results. The fifth and last bateh of the' toner was made using up stumps of lots 1, 2 and 3 .that had been accumulating ever the pJLst five,. months. This bateh was lighter end brighter, v.s. weaker and si, ysllOWer than CS-7853, The drying method continues as heretofore, consisting of drying for 48 hours at 140 F with subsequent drying overnight at 180F. This method secures a practically bone-dry eolor and results in a darker bluer and stremigar product, Crstv. Afl^est ion has been raised as to the uniformity of the var ious lets of Llthosoi Red 2-B die, BAeh let is eempesed of several semi- works batches the dye made at the Wbfks with no special attempt being made to secure a unif orm mixture of the various batches, A series of rubouts have been made to cheek this point by rubbing vat control samples on batches of toner made on the CS-7853 standard formulation but using different barrels of Hthoeol 'Red. 2-B, lot 3, It was necessary to use toner vat control samples on these lots because in all but one case it was necessary to use the toner before extension of HM-7909-D batches to secure the san<p3%s desired* By this method toner manufacture from barrels 1, 3, 4 end 5 teen? compared with each other. In all eases the samples wore rb-dried ovornlght at 180 F in order to decrease the chance of variation due to moisture absOrption. From these results it appears that barrels 3 and 4 give practically equal results with both j DUP050315953 si. light results vs. barrel 1* Barrel 5 gives results intermediate between barrel 1 and barrels 3 and 4 being v.s. light versus barrel 1 and v.s. dark versus barrels 3 and 4, Barrels 1, 3 and 4 checked fairly elosely in strength and tint With barrel 5 giving v.s. bluer results. This un-uniformity of the dye makes it difficult to measure the effect of variables in semi-works research. Dependable results could only be secured by dissolving a large quantity of the dye and using aliquot portions for experimental batches or by more intimate mixing of the dye pulp in a suitable pulp mixer. Another difficulty has been encountered during the month on this toner. On making a rub out of the old CS saaple OS-7745 versus the new 03 sample 03-7653 it was found that the 03-7653, originally v.s. light, v.s. weak and v.s. bluer vs, OS-7745, now gave darker and stronger results. Re-drying the CS-7745 as a possible reason for this change gave praetioally the same results and inasmuch as both samples were taken from the corked OS saaple bottles there was little if any possibility of moisture absorption. On rubbing- other samples that had , been previously rubbed versus both samples it was fbund that the CS-7745 had changed and that the CS-7853 eheoked the original results. No explanation for this change can be given. j ; j : ! | | | Two mixes have been made from Seal-Works production, of RT- ? 7853-D to date, the first mix totalling 778 lbs. is si. light and bright, s. strong and v.s. yellow vs. ^GS-7853 and 1ms been placed in standard stock.

The comparisons made were ; with RT-30Q-D, r t -s v o -B and 461-23A (buffered alkaline coupling modifies- 3 tion of RT-379-D). 461-23A method was decided upon. This foimula,pio- 1 duoed dark, bright material of good strength and thb duplicabilitytwas J found to be consistent. 461-23A formula has the shortest coupling 'time * I and it seems that the stability depends largely on it; Increase in i coupling time results in offshade material of poof strength. This is apparently due tc decomposition of the diazo as manifested by a change in crystal structure (Crystal growth during the prolonged eouplingiime) 1 The enlargement of crystals in the diazo and formation of crystal | groups was observed under the microscope* The cplctr of such, a dl azo I changes to a darker shade.

Increase-in time of agitation after coupling gave an increase in strength apparently due to a more complete coupling. Decrease as well as increase in Beta Napbthol seems to be detrimental to brightness. A slight increase in Beta Napbthol up to 3.3 resulted in a slight increase in strength and yellower tint. Decrease in sodium nitrite resulted in lighter, duller, weaker material. Brightness was improved by an increase in Para Soap, this (material being equal In brightness and strength to RT-379-D and of bluer tint.

Further work will be devoted to improving the formula in whieh sehaeffer Salt is used for darkening mabatons (472-17D). Im provement in brightness, strength and softness of texture are essential.

Also included in this report is one batch outstanding from last month. SUMMARY fc CONCLUSIONSi The outstanding batch and the first batch made this month were checks except for a change in the 'size of the batch, the first being,a< one mol charge and the second a three-quarter mol batch. In an attempt to secure light, blue and weak material four variables were introduced; , the ratio between the amounts of TUB aadfOESr used was change from 6l># --35# to 75#--25# respectively, the saount of caustic soda used in the coupling was reduced approximately 3-1/3# (3 lbs. on a 1 mOl charge), the calcium chloride used in the strike was cut 50# going back to the standard amount, and the temperature of development was increased to 160 F from 140 F. The results on these batches did not eheek, however, the first being lighter than standard and the second v.s. darker. This difference may have been caused by difference in quenching temperature due to the difference in size of the batch. Alkalinity of the coupling was; also a trifle higher in the second batch which would cause a darkening 'of the masstone. Both of these batches were on the yellow and strong side of standard which was not the result desired. The second batch was made to eheek the first except that a coupling time of fifteen minutes was used instead of the standard one-half hour* This variable had given bluer material in the laboratory. The results on this batch were also unsuccessful the. product remaining on the yellow side of stan&af^fc.' One batik is still in process and will reported next month. A satisfactory 1763 pound mix has beau made from current plant production. Results on this mix are reported in Table II and plant production tabulated in Table I.

Some of these controlling factors have been applied to plant mahufaetiire with generally the same results as obtained in the semi-works. SUMMARY & CONCLUSIGHSi A - Semi-Works Eleven batches of the G-7888-D shade green were stuck daring the IfTst month and a half in the semi-works. The control for these was a check on the yellow from a previous batch of G-317-D, SW-6808, but shaded to the extra light depth. This batch was light and very slightly olive la masstone, yellow in undertone and tint, and had much better light stability as compared to G-315-D standard. A decrease of fifty percent in speed of agitation gave a blue undertone, a slightly strong, blue tint, and a very slightly dark and olive masstone against standard, with light fastness equal to control. A decrease in. strike volume of 35$ gavi similar results except for having very slightly inferior light stability. Similarity was also noted in a batch In which the nitric acid .writs increased ap proximately 5$. The masstone of this lot worn slightly dark and blue, with v.v.s. worse light fastness. It was found that doubling the mount of sodium sulfide gave a dirty and olive material without affecting the light fastness. Reducing thaamount of sulfide gave a lighter, cleaner product with reduced light 'sbiSSlity. Omitting the sulfide gave a tinctorially satisfactory product with, however, distinctly worse light fastness. Thinking that perhaps some of the detrimental effect of the use of this reagent might lie in the alkalinity, one batch was ram as a cheek on control except that enough hydrochloric acid was added to neutralize the alkalinity of the sodium sulfide. Altho this product had satis factory tinctorial properties, the resistance to light was very very slightly reduejfd. Jfcte it: -'the batch was Struck with a small .portion of sodium sul- Mmm taken frofe the amount added before flooding and put into the strike solution. The result was a sightly light and olive masstone with a slightly blue undertone end t#it. Light fastness was not af fected. One batch Washed, shaded end pressed the same day gave almost similar results, ihe undertone end tint being slightly yellow against G-315-D, and checking control. It has been decided to use copper hydroxide in the washed yellow in the plant, especially in the ease of the dark shades, as the use of this reagent increases the stability of the color. Without it, the dark greens become very changeable upon standing in slurry or press, cake form. One semi-works batch mads oh this formula in the light shade had light fastness very slightly worse than control. DUP050315965 B; -.Plant - fire batches were struck during the month, two at G-7889-Dd&pth, two at G-7764-D and one at the G-7891-D shade. The first batch of G-7764-B was run as a cheek on 3W-6808, and was slightly blue and bright in masstone and very slightly blue in undertone against G-317-D standard* The second batch contained copper hydroxide and was similar except for a very slightly yellow undertone. The first batch of G-7889-B was struck on a yellow formula similar to the second G-7764-D one except for a fire degree increase in tempemture. The product was light and slightly olive in mass tone and very slightly strong and yellow in tint against G-315-D. a reduction of fife degrees in temperature, and the neutralization of the akalinity of the sodium sulfide with muriatic acid made the next hatch brighter in masstone, and bluer in undertone and tint. The batch of G-7891-D was light in masstone, and yellow in undertone and tint against G-318-D. This batch was struck on the SW-6808 formula with copper hydroxide in the washed yellow.

A satisfactory process has been developed and the problem has been turned over to the .Semi-Works for development. SUMMARY AND CONCLUSIONS The study of the revised Y-18G-D process was continuM from the past month. It waa found that using conditions similar to those in CS-7903$i i.e. heating after the strike and having a lead excess during washing, resulted in a satisfactory product* A further study of the revised CS-7903 indicates that the pigment is clean in masstone if the heating and washing cycle is correct. It is probable that- the conditions required on large scale production will have to be worked out in the Semi-Works. f The revised CS-7903 process has been submitted to the Semi-Works for development in preference to the revised Y-180-D process.

Altho definite c coolusions cannot be drawn from a limited number of experiments it appears that Summer conditions of high humidity and high water tem perature may have a slight detrimental effect on the tinctorial proper ties and the light fastness* Further evidence on this point may boob- ^ taimed in the Stet-Warks studies. A point which appeared of considerable importance in the Semi-Works studies was the purity of the lead nitrate used.

Lewis Chrome Orange may give a paint film increased impermeability possibly due to the plate like character of some-of its particles, a laboratory sample of Chrome Orange has been prepared with plate cyrstals which may be similar to the J.T. Lewis Chrcme Orange in behavior. Accumulating evidence indicates that the sole desireable v property of zinc yellow is the presence of water soluble chromate ions. A great reduction in cost could be obtained thru the use ef cheaper materials containing a greater percentage of water soluble ebronsite ions. For example calcium chromate will have a lower raw material cost than zinc yellow, it will have a higher percentage of soluble ohrornate ions, and it will have a lower specific gravity.

The main difficulty la. the process is evidently in the type of agitation which is both ineffective and Inadequate. Changes in the present equip* ment are planned end they should successfully surmount the obstacles thus far encountered. . SUMMARY & CONCLUSIONS: A total of nine purifications were attempted during the month only one of which reached the desired endpoint of a negative test for copper with anaemia. This batch was quite dilute, there being 9.15 square feet of lead surface for every one hundred pounds of lead nitrate? The amount of copper Initially present was slight and was removed in about four hours. In this purification, and four others comprising the last five made during the month, the agitator was run so as to pull thfe liquid up from the bottom rather than to push it along the bottom of the vat, as was fozmerly the ease. The high speed "Lightnin" mixer at present in use is quite definitely unsuited to the job in hand. It can eas ly be seen from the character of the copper deposits on the lead sheets that the agitation is inadequate in some sections while at the sene time it is so violent In others that it tears away the deposit already formed. As a consequence, it has been recommended that the present type mixer be replaced by the ordinary kind of sweep agitator. This change should remove the difficulty now encountered; There has also been trouble in cleaning the equipment after purification. In the present set up, the lead Sheets become quite dry in the tifft^squired- to run the purified liquor down Into the storage vat, and to f||||luthe purification vat. The. character of the deposit is such that upp haring bean dried, it earn only be removed with dif ficulty. la #d&r to obviate the 1$ effect of this condition a sprinkler eons isting of ef straight pipe grillin' transversely at isftHpie^eV was in stalled to keep the plates wet at all times. The plates thus treated are cleaned very easily. It is planned to install enough sprinklers to give the sane effect on all the lead surface. These changes, together with an additional outlet to enable the vat to be emptied in half the time, now required, are expected to make successful routine purifications possible.

REPORT -PRUSSIAN BLUE - B-14Q-B SUBMITTED ST: APPROVED BY: t DATE: JULY - 1935 FILE: KICK DLTJ3S- INTROSUCTION: About two months ago, the plant stated that they were encounter ing difficulty in standardizing Prussian- Blue, B-140-D for lacquer and requested the Research Department to make a study of the process. It was decided to first carry thru a study of moisture content to determine whether their is any relation between this and tinctorial properties. SUMMARY & CONCLUSION: Press cake samples of three hatches were dried in the laboratory electric even for varying lengths of time, pulverized and examined by rubout, lacquer and Dulux grinds. It has been found that plant batches of B-14Q-D vary consider ably from each other but that within reasonable limits, water content (determined by toluene distillation) has practically no effect on tinc torial quality in lacquer or Dulux. Neither was there any clear cut ef fect on tint. Standard B-140-D (lot 13466) contains 6.4$ of water. By long dryi&g at 140 it is possible to bring the water content to about 4 - 5# water. Under the conditions existing at the time of the experimental work, this was about as low as it was possible to go. Small samples were also held at 140' (in desiccators) at high and low humidity. This had very little effect; hbwever, it appeared that the sample which presumably contained the least water was slightly more bluish and milky than the abbagfa.. It is planned--to check this point. In view of our limited knowledge of the B-140-D procedure a general laboratory study is being started.

No improvement in flow of the 2:3 ink wae obtained but here again sppe ; treatments, Ba Hydrate, Glucamine, Metso, Soya Lecithin, gave the idle' a glossy smooth appearance which ie usually Indicative of good flow, 'sev eral add type agents, such as old* and naphthenic acid were tried which gave interesting results. Altho the 2:5 inks appeared short and buttery on di luti on to approximately 15$ pigment they had better flow than the control, espedggijr oleic add, and the alkaline treated ides had lass flow than the tfiitrol. An ink exhibit of a 2$ Barium Hydrate treated ink will be sft<i| to the customer.

T>w T>TfllflgWH<^ BATE* JULY - 1935 INTRODUCTION ir Investigations on the preparation of color lakes of Tat dyes were confined to comparison of the three Pansol type dyes of the SZ, GD and BP brand3, and. eulfonated Fomsol Blue B. SBMKARY & C0N0LUSI553 The Ponsol brand of vat dyes are Indanthrene types,and the 52 > GD and BP brands differ only slightly chemically, e.g. the 52 is the acid pasted straight amine snthraquinone condensation produet, common ly known as Ponsol Blue H, and the SB and HF are the corresponding mono chlorinated and diehlorinated products, respectively. All three sere similar in lightfastness as judged by fade-0-meter tests, and differ only slightly in tinctorial properties as judged by comparisons of their alumina hydrate lakes. However, the SB and BP dyes are much lower in cost than the 52 brand and in some respects superior tinctorially. Lakes of the SZ and SB brands are practically similar in shade and tint, whereas the HP product i3 appreciably redder. The use of erode dye paste, that is, dye which has not been standardised by either mechanical or chemical treatment in order to render it particularly suitable for the dyeing or printing df tex tiles, results in lakes superior tinctorially, especially in strength and cleanness of shade and tint, than the regular double paste brands which have been standardized for textile use. In the ease of Ponsol Blues 52 and 5B and Ponsol Jade Breen, the crude pastes yield alum ina hydrate lakes superior to lakes prepared from the regular double pastes, in tinctorial properties. Lakes of aulfonated ponsol Blue R, mentioned in the previous re port, are much blacker in masstone and much greener in shade and tint than lakes of ponsol Blue 52 (BP-121-D} and Indanthrene Blue 2 SNSL (BP-86-d ) . Thb alumina hydrate lakes of this new Vat dye are ai ightly more brillias^fl^tiian lakes of Ponsol Blue 52. While the sulfonation of Ponsol Blu#B has net resulted in a water soluble dye, nevertheless it possesses merit, since lakes prepared therefrom are appreciably greener than those of Indanthrene Blub 2 SNSL, and with such a product plus the red Ponsol Blue BP lake it appears possible to match tinctor ially any of the shades obtained with Ponsol dyes between these two extremes.

SUMMARY & CONCLUSION: The present method of preparing the pyroxylin lacquer to make Fabrikoid, comprises chiefly ball-milling -the dry pigment with a vehicle (Castor Oil) for several hours (the time depending an texture and ease of dispersion} and then stirring with cellulose nitrate pins solvents. It has been hoped that by using plgme&tlr already dispersed in oil the ball-milling phase could be eliminated or considerably shortened. In the former case, the final mixture Would be made by simply adding enough oil to obtain a definite ratio of pigment to oil, and stirring with the other ingredients. Tests made recently on our CS-7751 type of ink indicated * a decrease in time of ball milling over the standard GX-309-D. In fact the ball milling could be eliminated but in this ease the stirring re quired was so long as to make the method impractical. With this in mind several S mapleS of castor oil treated (3, 7, 25 and 40$ of oil} GX-309-D Extended Green,were prepared' in the laboratory. From this series it is hoped to secure either an ink type pigment that will obviate the ball mining step- of the process, or a substantially dry color readily dispersible in castor oil. These samples are now being tested at Newburgh. EXPERIMENTAL DETAILS: .

These samples were not from the same original charge of dye. Lakes were prepared from these dyes both by the BP-121-D method {alum-dye mixture precipitated with soda ash) and by the method of adding the dye slurry to a washed hydrate 3 lurry. Evaluations ware made, by rub outs of the divided lakes and by flushing, of the pulp lalis into varnish. Comparisons were alsomade against the straight dyes both dired out and flushed out. The following conclusions were drawn from the results of the above experiments which were confirmed by a duplicate experiment.

Humidified drying was given another trial! No active work was done in the plant by the Development Section except in making two batches of RT-20Q-B for use in rubber. Production of RT-210-D and RT-15S-D was under plant direction. STBaSARt & CONCLUSIONS: In the Semi-Works the closest match to RT-232-D was ob tained by use of a snail amount of Mono Acid 1 as previously done in the plant. A close second was a batch with 50% of the formula amount- of Para Soap, altho a check run on this formula was slightly farther off* The full amount of Para -Soap gave a prodnct too yellow in tint. y At best the products obtained"are somewhat toe light, while only equal in strength aa compared to standard. The use of Mono ifcid L Is not generally recommended because of its apparent effect on solubility of the Toluidine and perhaps on dispersion in seme vehicles,. _ Redaction in excess .of beta naphthoi by 56% had no effect*. ' I - An increase in amount of nitrite to obtain a fairly - positive test in the dlazo was not detrimental to brightness as expects^,. i A more complete diazotization was obtained and this Amount (17.5# aitisfeh'"i per 0*25 mol charge) was adopted. 1 Simiarly arise in diazotization temperature (45 - 50 1 instead of32.35?) had no harmful effects., A very^eiightincrease in strength was noticed on s control sample but this disappeared on finished grind. . X Increase in coupling temperature and reduction in amount of blearbonatSlMd the usu#l effect but the increase in depth is of course less tfSIfc'the decrease in strength. | f f s ] .A'variation suggested by the plant - coupling at 40 F with subsequent heating to 166 F - gave a light, yellow tint product having poor texture. Reduction incoupling volume and in amount of bi carbonate used did not improve the product. A comparison of four different lots of M.N.F.'T* including one from Sherwin-Williams gave different results depending apparently on the amount of Para Soap used. With 50% of standard amount of Para Soap, the Sherwin-Williams material and Lot 413 (Du Pont intermediate with special dispersing agent) gave weaker and bluer products than did Lot 405 and 426 {ha old and a recent lot of M.E.P.T*). The latter were close to standards However, with 78% of standard Para Soap all four lots Were close to each other and to standard (v.s. light & bright in DUP050315998 masstone). Tbe&mos t recent lot {#4$S) was also slightly weak and blue even with the-Sigber amount or Para Stop, but it gave a somewhat darker masstone. It say be concluded that differences in these materials may show up under certain conditions hut that they can he eliminated by proper adjustment. Differences in dispersion in water were noted. The Sherwin-Williams M.N.P.T. wets up very readily in water. Lot 413 was a slight improvement over other lots of Dii Pont intermediate. Lot 436 was characterized by thickness of the piulp which it foxmed in water. The drying experiment (140 F at 30$ humidity) showed no improvement under these conditions* In tiie plant two batches of RT-200-D made without use of Mono Acid, tested Q.K. in rubber. The formula was same as a pre vious batch of RT-158-D with seme modification on the second batch.

The first hatch was made to check the standard HT-283-D form ulation except for a 10# increase in "I" Rosin (150# - 165#) and a two pound cut of the caustic soda in the coupling (1GS# - 100#) This pro duct was s. light end muddy, s. strong and blue versus the RT-283-D standard and dark end muddy, strong and clean versus the' RT-242-D^^^^ Cheeking the first hatch except increasing the rosin anotherr ten pounds {165# - 175#) and increasing the caustic soda in the rosin soap hy 10# (3# - 33#) gave a product lighter and muddier, v.s* weaker and v.s. bluer than standard RT-S83-D* Headings vs* the RT-0S2-B std. were v.e. dark, less chalky - v.s. yellow a clean 0 vvs strong - clean. The third hatch was made to cheek the first hatch except that the caustic soda in the coupling was increased hy 7# (100# - 107#) Results remained on the light,weak and blue side versus the standard. Finally, a dark, v.s. strong and v.s. blue and clean hatch was secured by modifying the standard BT-E83-D formula as follows: increasing the caustic soda in the coupling hy eight pounds (102# - II#): to secure a distinct Clayton Yellow test (pH above Hr*), increasing the rosin byn25 lbs. (150 - 175#) and increasing the eamstle soda in the rosin soap by 20# t80- 36#)* Btag&m and final batch reported this month an attempt was made to eSppfa a product epproMmately v.s. dark' vs. the standard. A check to tPPlsst batch was made except that the caustic soda in the coupling showed a v.s. Clayton Toller teat (pH - 11.5). The product ground out vs. light, v*s. strong and v.s. yellow and elean vs* the 9 RT-883-D standard. From these results it appears that the pH of the coupling plays an important part in tihAiiy- determining the lightness or depth of masstone in this color* Because of the moisture absorbing character istic of caustic soda a constant weigjit of the alkali does net always guarantee the securing or :a-coifahenf^;pR- as is proven bythe third and fifth batches reported this month. i&bth hatches were made using 107# of caustic soda in the coupling with/the resultant pH determinations being 10*7 and 11*5 respectively, the pH determination after the devel opment dees not seem to he of importance except as controlled hy the pH DUP050316003 of the coupling. The alkalinity of the toner slurries after development has been within a two-tenth' pfi range (11.4 .1) with noticeable differences inecoupling alkalinity, a coupling pH of above 11,6 (dis tinct Clayton tallow test together with the use of 175 lbs. of rosin has given very dark material. A more desireable v.s. dark material can probably be secured by deoreasisg the rosin slightly or by lower ing the pH of the coupling to 11.6 or 11.7.

TONERS INTRODUCTION: The Hamcan Color Works submitted eight samples of maroons to the Du Font Company, which possessed, it was claimed, "high hiding power* brilliancy, depth of shade, remarkable dur ability and light fastness for use in both synthetic and pyroxylin vehicles.1* Parlin and Philadelphia have examined these maroons and have expressed the opinion that they were not particularly in teresting tinetorially but fi&t theydid possess hiding power superior to our own standards. They also felt that the muddy tones of the Harmon Maroons could easily be obtained by toning their present maroon pigments. However, it was decided to examine these products in our laboratory and to develop a light and a dark maroon of maximum hiding power, -vdiich would cover the depth range of the Harmon colors and at the same time maintain, as much as possible, bril liancy of color. SUMMARY & CONCLUSIONS: The following is a tabulation of the eight Harmon Maroons including hiding power (by Parlin}, prices, analytical data and color comparisons (lacquer} with RT-354-D.

Toluidine Maroon A-643 is really a dark red, intermediate in depth between a dark para red and a maroon. Toluidine Maroon A-641 is lighter and duller than RT-354-D but darker than RT-347-D. Converwell Victoria Maroon A-658, Tolui dine Victoria Maroon A-659 and Coverwell Garnet a-663 are close in depth to each other and to RT-354-D, but browner. The remain ing three, Coverwell Garnet A-664, Victoria Maroon Extra Deep A-649 and Toluidine Maroon Extra Deep A-650, are close in depth to each other, and distinctly darker and browner than RT-354-D. The Harmon products all bleed somewhat in lacquer. Chemical ' spat" tests indicated that these maroons con tain mixtures of the Toluidine Maroon (N.M.F.T. - N.B.S.) and the Lake Bordeaux B types (T.O.B. - B.O.N.) In C-37517, C-37518 and C-37519, the organic oolor is probably mainly of the Tolui dine Maroon class. Incidently, these three maroons have the highest selling price. In the others, the chief organic con stituent is probably of the Lake Bordeaux B type. All of these maroons are very weak tinctorially as compared with our own standard maroons. Chemical analyses shewed the presence of sulphides in six of the eight samples. The two darkest pigments gave no test for sulphides. (C-37521 and C-37519). The manganese salt of Lake Bordeaux B (RT-347-D is probably present in those cases where this type of organic maroon was indicated by ''spot" tests since in three samples which were analyzed, manganese was found. In hiding power, these maroons are distinctly better, than our standard maroons shewing, in some cases, about twice as much hiding power. The factors contributing the superior hiding power to these pigments have not been definitely estab lished. The cadmium red pigments are not so good in hiding: power as RT-347-D when compared on an equal pigment basis. On the other hand, the ceramic cadmium reds, i.e., unextended, possess slightly better hiding than RT-347-D. There were indications from our analyses that these maroons contained themnextended cadmium reds since no barium sulphate was found. However, the two samples which contained no sulphides possessed better hiding power than RT-347-D, consequently some other factor besides cadmium redtsust be responsible, at least in these two cases. The iron cohUents were too low to suppose that iron oxides were present* Carbon Black was not identified, altho it would be rather difficult to recognize black in small amounts. We have known that the addition of small amounts of Pigment Green B im parts depth and hiding power to maroons but it would be difficult to identify this pigment in a mixture of maroons, because the iron content would only be increased slightly by its addition. With respect to the possible durabilities of the Harmon maroons, it may be anticipated that those products which contain cadmium red would probably be unsatisfactory in Duco on the basis of past experience. In Dulux, however, cadmium reds are not objectionable even when admixed with maroons within certain limits. In the case of the light maroon, C-37518, the presence of cadaium red would probably render it unsatisfactory in Duco, and the presence of the Toluidine Maroon type; might make it un satisfactory for Dulux purposes* DUP050316013 4 Influenced by the dark, muddy masstones and the very weak undertones of these maroons and knowing that these proper ties are exhibited by undeveloped toners, experiments were run to determine the effect on hiding power of undeveloped maroons. The results showed tendencies towards increased hiding power but the colors were also quite brownish. No further attention was given, therefore, to this method of procedure. The addition of 3$ Pigment Green B to the standard maroons, increased the depth of masstone considerably and improved the hiding power to within the range of the Harmon colors. The further addition of about 2$ of titanium dioxide to the mixtures of maroons and green brightened the color appreciably and result ed in a slight increase in hiding power. The practice of adding Pigment Green B to the extent of 3% to maroons was sanctioned by Parlin far Duco purposes as well as the addition of titanium dioxide. For Dulux purposes, no definite informationis available on the effect of Pigment Green B on the durability of maroons, but the addition of even as small an amount as 1$ of titanium dioxide to maroons is ob jectionable in Dulux because of excessive chalking. As a counter offering against the light Harmon maroon, C-37518, a product has been developed in the laboratory which is brighter but slightly poorer in hiding power, and which should be durable in Duco. The addition of some titanium dioxide improves the hiding power and brightness. This product, 424-25, was pre pared on practically tho same formula as RT-354-D except that the conditions for producing depth were eliminated. T.O.B.-W. was omitted and excess sodium nitrite and B.O.N., which are neces sary for the formation of a small amount of a green pigment, were eliminated from the formula. The final product is practically identical chemically with ST-354-D but considerably lighter. Other possibilities for the light maroon are Grela Red Dark, CS-7400, meta nitro para anisidine red, CS-7699, and the manganese toner of Hello Bordeaux BL, 03-7407. For_Duco purposes, CS-7407 is non-durable; CS-7699 and CS-7400 have not been exposed sufficiently. For Dulux use, these three light maroons seem very promising. CS-7400 and CS-7407 have shewn satisfactory durabilityafter 20 months in Delaware. CS-7699 was satisfactory for 7 months. The ipnganese toner of Hello Bordeaux BL, CS-7407, be sides being b^ghter than Harmon's Toluidine Maroon A-642 (C-37518) is substantially equal in hiding power and is non-bleeding. The above has been discussed with representatives of Parlin and it was agreed that Newark submit samples of RT-354-D, RT-347-D and RT-297-D with and wilhout 3% Figment Green. B for ex posure tests to be run along with the Harmon colors. Parlin will also add 8# of tit anitan. dioxide to the above. A sample of the light maroon, 424-25, will also be submitted,which will be ex posed with and without titanium dioxide (5 and 10$}. It would be useless to submit for Dulux tests the sam ples of RT-297-D and RT-354-D containing Pigment Green B because of the poor durability of the former and the gellation tendencies of the latter. Mr, Stuart of Philadelphia was not interested in a darkor RT-347-D, therefore, the sanplo of RT-347-D containing 0 DUP050316014 m 5 green will not be submit te".. A sample of 424-25 (light RT-354-D) will be sent to Philadelphia, however. The following tabulation gives comparisons of the samples to be submitted to Parlin with the samples of Harmon's lightest and darkest products: Hiding Sample DescriptionPower * Color Comparison 424-22A 424-22B 424-23A 424-23B 424-24A 424-24B 424-25 C-37521 C-37518 RT-354-D control 50 RT-354-D 4 3% Pig.Gr.B 30 RT-347-D control 40 * f 3# Pig,Green B 21 RT-297-D control *50 ** 3# Pig.Green B 32 Very light RT-354-D 35 Victoria Maroon Ex.

About 2% of titanium dioxide brightens and in creases the hiding power of these colors. In the case of the light maroon* 424-25, its hiding power is not quite equal to Harmon's C-37518, but its color is decidedly brighter. In ad dition it contains no cadmium and is non-bleeding. Its hiding power and brightness may be enhanced with titanium dioxide. EXPERIMENTAL DETAILS: See Notebook No-. 424, pp. 52-77 ii. i DUP050316015 SUBdlTTED BY!

Consequently some studies were carried out on the Isolation of the dye and subsequent conversion to the strontium toner (RT-559-D). STMtfARY fr CONCHBIONS: Last month*s report mentioned the development of formula 463-20C which gave a superior color than standard RT-359-D formula. This month, it was found that the superior qualities of the 463-20C method were maintained when the soda" salt was isolated and later con verted into the strontium toner. It was also found that the isolated dye formula 463-25D ' gave almost identical results with those from the direct laking for mula, 463-20C The Isolated dye apparently may be used either in paste cr dry form. Ageing of the dye (paste dr dye) had an almost negligible effect upon the toner. 463-25D (Isolated dye formula) is lighter and brighter in masstone, slightly more bronzy, slightly stronger and yellow in tint than standard RT-359-D. Baking of 463-25D at 100 C darkens the masstone slightly, decreases the bronze considerably and makes the tint slightly bluer. me consideration should be given in the semi-works to humidified drying of this pigment. Since standard RT-359-D contiins about 4$ of moistufe (volatile' at 110 c), the cake must be dried either by humidified drying to a 4# moisture c tent or dried in the regular manner and then rehamidlfied to the proper moisture eonteat. It must alt-be remembered that beyond 4# in moisture the depth of masstone and the tint do not change but that the color becomes correspondlngly weaker. Moisture lower than 4$> will result in a change toward a darker masstone and bluer tint. The 463-2 5D formula has been submitted to the Development Section to prepare a quantity of dy#*to be set up as a standard for the Dye works. It is also planned to continue work in the laboratory on the problem of bronze elimination, starting from semi-works prepared dye. vcTP-mttmfFPAL DETAILS: Notebook No. 463, series 25 & 26. ------ Dye WorkB Notebook No. 1740 (Dr. C.K.

An orientation experiment on the substitution of 3 nitro 4 amino ethyl benzene for 3 nitro 4 amino methyl benzene (METPT') in Taluidine Red RT-3B6-B was carried out, and the preparation of dry color lakes from water dispersible Pigment Green B was repeated in order to con firm the original results, gmttfARV 4TTO C0HQLU3I0HS Laboratory studies on both CS-7779 and 05-7807 are drawing near to completion, the desired objectives having been attained. An appre ciably darker CS-7779 than the original sample has been consistent^ prepared by reverse strike and other lean important modifications of the original process. However, the preduet is fuite hard in texture which might not be objectionable provided it can be disintegrated properly. Investigations on this product disclosed a mush lighter product than the original sample, the former apparently being the true form of this lake. This preduet is appreciably softer, and gives a thinner and longer ink than the original sample. Altho 05*7779 is 7ery gftable and its du.plieability very consistent, it can be varied appreciably in physical and tinctorial properties owing to its excel lent flexibility and response to the action of variables. The Dyeworks study of the dye of CS-780Y has been completed, and a large sample of laboratory prepared dye has been employed in a stpdy of the effect of. variables and the development of ap^.Jmproved process; for the lake. Here again, a wide range of physical and tinctorial properties can be obtained by the action pf processing variables. The study, which has been practically completed, has resulted in a much lighter gad brighter masstone product and an improved taking procedure eaH#ed with the original J33-7SQ7. The principle change in the forsa^Ktias been the proper control of the hydrogen ion con centration ofNfehe development of the lake. Substitution Of 5 nitro 4 amine ethyl benzene for 3 nitro 4 amine methyl benzene (1SJFT) in HT-385-D results in a lighter, much weaker and more oil soluble pigment than Toluidine Bed. Altho the replacement of. the methyl group in MBF1? with an ethyl group is inter esting theoretically, the new product possesses nb merit commercially. The preparation of dry colors from dispersible Figment Green B has been cheeked, and the original results reported in June have bean confirmed. The combination of 5 sulfo 6 chlor 2 amino benzoic acid with B-Salt yields a soluble orange colored dye, the baritta salt of which 'i $ *> DUP050316018 Si is insoluble in water and exhibits only little promise as an orange pigment.

Acidification prior to the strike gives results practically similar to acidification subsequent to the strike. Increased time of boiling development from 5 to 30 minutes has no appreciable effect upon the pigment. Reverse strike at rapid rate results in darker products than slower rate of strike. Reverse strike results in darker products than direct strike. Direct strike at very slow rate results in pro ducts very much lighter, softer and somewhat weaker than products struck at rapid rate.

StMMAHY & CCaSTCLBBIOliB: One batch, one-fifth standard formula size, was made in the Semi-Works to eheek laboratory experiment 1793-5C. Du Font Lithos ol Brilliant Blue E, Lot 23 was the dye used in this hatch. After pressing the hatch was split and one-half dried in the Electric dryer at 140 F and the other half dried in the E. & 3. dryer at 140r F 40$ humidity. Both of these materials were satisfactory giving con&iderahly stronger, greener and cleaner results together with a high# ' finish than the competitive sample. Both were greener and ellght3|r ft weaker but were very slightly higher in finish than the BL-159-D standard. Humidified drying gave slightly greener and,cleaner results compared with ordinary drying but showed no Improvement in finish. Samples have been forwarded to the Sefvlce Laboratory for complete ink evaluation testa and results will be repo rted next month.

The only difference between this and previous satisfactory batches was that different lets of Thioflavine TCH and Lithosol Blue 60 were used in making the toner. The tester con trol was satisfactory* The second batch was made using one-third the amount of t base and two-thirds the amount of toner that was used in the first batch in order to make strong material for shading purposes* A mix was made but was unsatisfactory because of the red and dirty tint. Both of the above batches were pulverized la the plant. The next two batches were made one-third the size of the first batch except, substituting Duponol WA for the Para Soap in the toner; this variable was reported in the December, 1934 report. Both of these batches wore strong, bide and clean. / grinding studies were then-run in the Semi-Works on one-half pound samples (previously plant- grbund) Of the first two batches* SUMMARY- ft CQNCLUSEOSS: ^ The S^llfkro' PulVeri^^ Tlds used using as the setup- 9600 R.P.M. and .QBVlneh acreea* Briiiaialb on theae two re-ground samples showed oennjmM* improvement?-; im--;stfaBath .over the original material, so both of tWfWntehes were rdg^i^d'in the Simi-Works 12" pulverizer using 4700 s|pi;i. and the with stirrup hammers. These reground batcher them brushed oui dtrong versus the BE-149-D stand ard, but still remained too red and' be satisfactory for shipment. Satisfactory mixes totalling 1031 pounds were finally made using the two reground batches apd the two blue and.clean batches.
