The B-216-D treated product was about 10$ strong versus control to which naphthenic acid Is added. Use of resinous oil instead of naphthenic acid represents a savings of $0.46 par 100 lbs* which is considerable on a volume color. The RT-521-D treated product was about 15$ strong versus control and the RT-427-D treated product was about 30$ strong versus control. The control, experimental product, and standard were about equal throughout in wedge grit in each of the three cases. BT-181-D and RT-530-D were weakened very much by the emulsion treatment The rest of the pigments were unaffected. m* SIMM.msasa. ----=7 Untreated plant slurries were obtained for use in this work. Solids content of each slurry was taken and one hundred grams (drip basis) of each were filtered and as control and another one hundred grams w^) treated with resinous oil emulsion (10 parts color/ 1 part emulsion) prepared according to K-2274. Samples were sent to the Ink Laboratory where wedge grit grinds were made. Samples of the inks were saved at 2L, 4L, oL, IT, 31, 6T. Rate of strength development was run on each set of inks. Results follows BP-173-D BT-181-D B-216-D YE-421-D RT-354-D RT-427-D RT-443-D RT-J21-D RT-530-D Treated product ggi,M .SflflteL at 52* 40$ weak 9$ weak equal 10$ weak 30 weak 30$ strong 20$ weak 20$ strong 15$ weak (Treated product ffaflgfi.iteli__ vs-control ) low throughout eqnual throughout gains less strength slightly high II ft equal throughout ft ii Dilution of the treated pigment due to retention of Resinous oil would warrant 10$ weakness.
