Abstract

Abstract A silver halide color photographic light-sensitive material is disclosed, comprising a support having provided thereon light-sensitive silver halide emulsion layers, wherein on the outside of the light-sensitive silver halide emulsion layer positioned farthest from the support, a layer containing silver halide fine grains of about 0.2μ or less in average grain size is provided, and in the silver halide color photographic light-sensitive material at least one compound represented by the following general formula (I) is present: ##STR1## wherein M represents a hydrogen atom, an alkali metal or a quaternary ammonium group, X represents COOM' or SO 3 M' (wherein M' represents a hydrogen atom, an alkali metal or a quaternary ammonium group), n represents 1 or 2, R 1 represents a group capable of substituting on the phenyl group, and m represents 0, 1 or 2.
