A novel silver halide color light-sensitive material is provided comprising a support having provided thereon at least one light-sensitive emulsion layer containing surface latent image type silver halide grains, wherein the light-sensitive emulsion layer comprises a photographic emulsion containing silver bromochloride grains substantially free of silver iodide and having at least 90 mol% of average silver chloride content, the silver bromochloride grains having a localized silver bromide phase on the surface thereof in a discontinuous or isolated state, and at least one pyrazoloazole type coupler represented by formula (I) and the light-sensitive emulsion layer or at least one of other hydrophilic colloid layers comprises at least one compound represented by formula (II-a) or (II-b): Image (I) wherein Za and Zb each represents a methine group, a substituted methine group or -N=; R1 represents a hydrogen atom or a substituent; and Y1 represents a halogen atom or a group which can be released upon coupling reaction with an oxidation product of an aromatic primary amine developing agent (release group), with the proviso that a dimer or higher polymer may be formed via R1, Za, Zb or Y1: Image (II-a) Image (II-b) wherein R11 represents an alkyl group, an alkenyl group, a heterocyclic group or an aryl group; X1 represents a hydrogen atom, an alkaline metal atom, an ammonium group or the precursor thereof; V1 represents an oxygen atom, a sulfur atom, =NH, =N-(L)n'-R12 in which R12 has the same meaning as R11; L represents a divalent linking group such as =N-R13, Image , Image , Image , Image , -S- . Image , Image in which R13, R14 and R15 each represents a hydrogen atom, an alkyl group, or an aralkyl group; and n and n' each represents an integer 0 or 1.
