Abstract
623,448. Stabilizers for photographic silver halide emulsions. KODAK, Ltd. July 30, 1946, No. 22695. Convention date, July 30, 1945. [Class 98 (ii)] Photographic material comprising a support carrying a silver halide emulsion contains in fog-inhibiting amount an aldoxime of the formula HO-R-CH=N-OH, wherein R is an ortho-divalent benzene radical. Aldoximes specified are salicylaldoxime, 3-methoxysalicylaldoxime, and resorcylaldoxime. The aldoxime may be incorporated in the emulsion or in an overcoating or substratum layer, and prevents fog due to copper catalysis. Examples are given showing the reduction in fog density obtained by incorporation of the compounds in silver halide emulsion. The effects obtained by the use of oximes of m- and p-hydroxybenzaldehyde and of salicylic and anthranilic acid are discussed.
