(57) [Summary] [Purpose] First, to provide a novel photographic cyan coupler used as a material for a silver halide color photographic light-sensitive material, and secondly to change the hue caused by heat, humidity and light. Provided is a silver halide color photographic cyan coupler capable of forming a color image which does not occur. [Structure] Photographic cyan coupler represented by the general formula [I] [Wherein R and Y represent a hydrogen atom or a substituent, and E WG represents an electron-withdrawing group having a Hammett's substituent constant σ p of 0.3 or more, and X represents a hydrogen atom or a group capable of splitting off upon reaction with an oxidant of a color developing agent. ] |
