摘要:
A silver halide color photographic light-sensitive material comprising a support having provided thereon: at least one yellow-color-forming light-sensitive silver halide emulsion layer; at least one magenta-color-forming light-sensitive silver halide emulsion layer; at least one cyan-color-forming light-sensitive silver halide emulsion layer; and at least one light-insensitive non-color-forming hydrophilic colloid layer, wherein at least one layer of said at least one cyan-color-forming light-sensitive silver halide emulsion layer contains at least one cyan-dye-forming coupler having a pKa of not more than 8.7, and wherein said at least one light-insensitive non-color-forming hydrophilic colloid layer contains at least one compound represented by the following formula (I): wherein R1, R2, R3 and R4, which may be the same or different, each represents a hydrogen atom, an alkyl group or an aryl group; and R5 represents an aryl group; provided that the total number of carbon atoms included in R1, R2, R3, R4 and R5 is not less than 14.
