Abstract
A silver halide photographic light-sensitive material comprising a support bearing thereon at least one silver halide emulsion layer, in which at least one of phenol cyan couplers having Formula (I) below and at least one of non-color-developable and diffusion resistive phenol compounds are contained. ##STR1## wherein, R.sub.1 represents a ballast radical necessary for endowing a phenol cyan coupler having Formula (I) and a cyan dye to be formed by the above-mentioned coupler with diffusion resistance; Ar represents an aryl radical; and X represents a hydrogen atom or a radical capable of splitting off through a coupling to an oxidant of an aromatic primary amine color developing agent.

A silver halide photographic light-sensitive material comprising a support bearing thereon at least one silver halide emulsion layer, said silver halide photographic light-sensitive material characterized in that said silver halide emulsion layer contains at least one phenol cyan coupler having the Formula (I) ##STR13## wherein, R.sub.1 represents a ballast radical necessary for endowing the phenol cyan coupler having Formula (I) and a cyan dye produced by the coupler with diffusion-resistance;
- Ar represents an aryl radical;
- and X represents hydrogen or a radical capable of splitting off when coupling to the oxidant of an aromatic primary amine color developing agent and at least one non-color-developable and diffusion-resistive phenol compound having the following Formula (IV):
- ##STR14## wherein, Z represents an alkyl radical, an alkenyl radical, an aryl radical, a cycloalkyl radical, an alkylcarbonyl radical, an arylcarbonyl radical, an alkoxycarbonyl radical, an aryloxycarbonyl radical or a cyano radical;
- R.sub.8 represents a monovalent radical capable of substituting a hydrogen atom of the phenol ring of said compound selected from the group consisting of halogen, alkyl, aryl, heterocyclic, alkoxy, aryloxy, alkylcarbonyloxy, arylcarbonyloxy, hydroxycarbonyl, alkoxycarbonyl, aryloxycarbonyl, alkylthio, alkylcarbonyl, arylcarbonyl, acylamino, sulfonamide, carbamoyl, nitro, cyano, alkysulfonyl, alkenyl and cycloalkyl radical, provided that when said phenol compound has two substituents represented by R.sub.8 at the both ortho positions of hydroxy group thereof at the same time, said two substituents are unsubstituted normal or secondary alkyl radicals respectively and n is 2.
