Abstract (en)

A silver halide color photographic light-sensitive material includes a support and at least one hydrophilic colloid layer formed on the support. The hydrophilic layer contains a coupler compound which is represented by formula (I) below and has a high dye formation rate and a high color forming density. This silver halide color photographic light-sensitive material can achieve an improved sharpness and a high sensitivity: Formula (I> A-(SO2NHCONR<1>R<2>)n (wherein A represents a coupler moiety, each of R<1> and R<2> independently represents a hydrogen atom, an alkyl group, an alkenyl group, an alkynyl group, an aryl group, or a heterocyclic group, and n represents an integer of 1 or more, if n being an integer of 2 or more, respective R<1>'s and R<2>'s being able to be the same or different, and A and R<1>, A and R<2>, or R<1> and R<2> being able to combine to form a ring.)
