Abstract
A silver halide color photographic material comprising a support having thereon one or more hydrophilic colloid layers, at least one layer which is a light-sensitive silver halide emulsion layer containing in the same layer a color coupler selected from a yellow coupler and a cyan coupler and at least one anti-fading agent represented by formula (I): ##STR1## The novel anti-fading agent effectively prevents yellow and cyan dye images from fading or discoloration, and does not adversely affect other photographic properties.
