Abstract

997,000. Photographic developers. EASTMAN KODAK CO. March 21, 1962 [March 22, 1961], No. 10755/62. Heading G2C. Photographic developers contain 2,4 dihydroxybenzophenone as an anti-stain agent. This agent may be added to developer solutions, dry single powder developers or combined developers and fixers. Alternatively this agent is added to a silver halide emulsion. Specified dry developers are those containing 2, 4 dihydroxybenzophene, phthalic anhydride, boric anhydride sodium metaborate and metaboric acid. Specifications 631,184, 729,862, 731,407, 731,419, 732, 945 and 898, 328 are referred to.
