Definitions
- R is an alkyl or aryl and m and n are each positive integers of 1 to 6.
- Silver halide emulsions and elements stabilized and inhibited against the effects of fog as described can be chemically sensitized, e.g., with noble metal sensitizers alone or in combination with sulfur or selenium sensitizers. They can contain spectral sensitizers, incorporated color-forming couplers, incorporated developing agents, other antifoggants, stabilizers, hardeners, plasticizers, coating aids, vinyl polymers, and other suitable photographic addenda such as described in US. Patent 3,297,446 of Dunn issued Jan. 10, 1967 (columns 4-9).

PUBLISHED SEPTEMBER 30, 1969 823,507 SILVER HALIDE EMULSIONS CONTAINING DISULFIDES AS FOG INHIBITORS Norman W. Kalenda and Dorothy J. Beavers, both Kodak Park Division, Rochester, N.Y. 14650 Filed May 9, 1969. Published Sept. 30, 1969 Int. Cl. G03c N34 US. Cl. 96109 No Drawing. 10 Pages Specification Photographic silver halide emulsions and photographic elements containing as an antifoggant and fog stabilizer a compound represented by the general formula:
wherein R is an alkyl or aryl and m and n are each positive integers of 1 to 6.
Silver halide emulsions and elements stabilized and inhibited against the effects of fog as described can be chemically sensitized, e.g., with noble metal sensitizers alone or in combination with sulfur or selenium sensitizers. They can contain spectral sensitizers, incorporated color-forming couplers, incorporated developing agents, other antifoggants, stabilizers, hardeners, plasticizers, coating aids, vinyl polymers, and other suitable photographic addenda such as described in US.
