COPT COtFIBUTXAL D8 F. F. EHRICH CC? d* Boom, Wild, d. * fully, A* Siegelt KSWAEK, SAT 29, 1951 For acase time we have been carrying on our program the completion of oar eolvent milling studies of Ponsol Violet 4 88 crude, with the object of obtaining realistic coat information and practical evaluation of Newark manufactured colors prepared from such dye. Delay in completing this program has resulted from restricted availability of the Ponsol Violet, since any crude provided to the Chemical Division for this purpose would be at the expense of acid pasted dye (N-612) required by Newark. At the SPC meeting on Say 25th, the Chemical Division representatives unanimously agreed to discontinue all work on the solvent milling of Ponsol Violet for the following reasons; 1, Because of the uncertain availability of Blue 28 from Orehsm, Sales will probably be faced with the necessity to obsolete BP-243-D. The alter nate procedure (*C* process), based on the manufacture from our own Blue IB (B-623) and Violet 4 BN (R*ol2) is unattractive costwise, and It is exceedingly doubtful if the availability of the stronger solvent milled violet is likely to influence the decision. 2 In general, the future of Ponsol Violet 4 BN colors is rather uncertain in view of the antici pated strong competition from Harmon*# Thlo Fast Bed H7-66Q6, which appears to offer better money value for the shading of CPC Blue. In view of (Ail uncertainty, we can not aspect any optimistic inf!, seams forecasts from *1*** <aa our Ponsol Violet codes. 3. Because of a critical selenium shortage, we do not know how long Orcham will be able to continue manufacturing Ponsol Violet 4 SB* They do not know of any other satisfactory catalyst.
