ABSTRACT:
A silver halide color photographic material can be formed which exhibits good storage stability and provides excellent sharpness and superior color reproducibility by incorporating therein a dye comprising an indole moiety having a methyl group substituted by an electron-withdrawing group at the 1-position and an acidic nucleus which are connected together via a methine chain. The dye is typically provided in a light-insensitive layer in the form of a solid dispersion. Specific embodiments include the combination of the indole-containing dye with a magenta dye, fogged silver halide grains, a DIR compound or a mercaptoheterocyclic compound.
