Abstract

1,037,646. Stabilizing photographic emulsions. AGFA A.G. May 29,1963 [June 9, 1962], No.21555/63. Heading G2C. Photographic silver halide emulsions contain a stabilizer of the general formula: wherein R 1 and R 2 are aryl, substituted aryl or heterocyclic groups and R 3 is methyl ethyl, aryl or substituted aryl. Examples of compounds are given wherein R 1 and R 2 are phenyl, p-methyl phenyl, p. methoxyphenyl, p-chlorophenyl, 3 : 4- methylenedioxyphenyl, 2-furyl or 2-thienyl groups and R 3 is methyl, ethyl, phenyl, p-chlorophenyl or naphthyl.
