Abstract
A light-sensitive silver halide color photographic material, comprising at least one photographic constituent layer containing a multi-functional dye which becomes substantially colorless in the presence of the oxidized product of a color developing agent through the reaction with the oxidized product, and becomes substantially colorless in the absence of the oxidized product of the color developing agent during the color-photographic processing step. According to the present invention, a color light-sensitive material containing a multi-functional compound having excellent sharpness, good color reproducibility and further excellent graininess can be obtained.
