| titleOfInvention | Photographic coupler composition comprising ballasted sulfoxide and sulfone and process for making same |
| abstract | (57) [Summary] [Structure] (a) A magenta dye-forming coupler compound, and (b) an amount of a sulfoxide compound or sulfone sufficient to improve the photostability of a magenta dye formed from the magenta dye-forming coupler compound. A photographic coupler composition comprising a compound, wherein the sulfoxide compound is of the formula: And the sulfone compound is of the formula: Wherein R 1 and R 2 are each independently a group of a substituted or unsubstituted straight chain and branched chain alkyl group, an alkenyl group and an alkylene group, and a substituted or unsubstituted phenyl group. Selected). Further, the combination of R 1 and R 2 contains at least 12 carbon atoms. The photographic coupler composition is free of phenolic compounds. The magenta dye-forming coupler composition has improved photostability. |
