Abstract
988,052. Photographic silver halide emulsions. ILFORD Ltd. Jan. 3,1963 [Jan. 16,1962], No. 1566/62. Heading G2C. The fog level in photographic gelatino silver halide emulsions sensitized with ethylene oxide condensates is reduced by incorporating therein at least 1 g. per g. mol. of silver halide of a compound of the formula wherein R 1 is -CH = NOH, -CONH 2 ,-CONHC 6 H 5 or -COOR (R is alkyl of 1-12 carbon atoms, phenyl or alkylphenyl), and R 2 or R 3 is hydrogen while the other is hydrogen, hydroxy, alkyl or alkoxy, or R 2 and R 3 together form a fused benz ring. Compounds specified are salicylaldoxime, salicylamide, gentisaldoxime, gentisamide, sallcylanilide, gentisylanilide, methyl, ethyl and lauryl gentisates, and amyl and phenyl salicylates. Specification 623,448 is referred to.
