Abstract
Abstract A silver halide color photographic light-sensitive material comprising A Support having thereon at least one light-sensitive silver halide emulsion layer and at least one non-light-sensitive hydrophilic colloidal layer, has (i) at least one magenta coupler of formula wherein R, represents a benzamido, anilino or phenylureido radical substituted by a sulfonylamino or aminosulfonyl radical, and R 2 represents an aryl or heterocyclic radical, and (ii) at least one development inhibitor releasing compound having a development inhibitor radical of formula wherein R 3 represents a hydrogen or halogen atom or an acylamino, alkyl, benzothiazolinylidenamino or phenyl-substituted alkoxy radical, or wherein is a five-membered or six-membered heterocyclic ring, provided either in the same layer or separately in different layers.
