Abstract
Abstract A multilayer color photographic light-sensitive material comprising a support having thereon at least two silver halide emulsion layer units, each of which is sensitive to radiation of a substantially different wavelength region within the wavelength region of from about 220 nm to about 800 nm and contains a color-forming coupler capable of forming a dye on coupling with an oxidized primary aromatic amine developing agent, with at least one of the emulsion layer units containing an ICC coupler represented by the general formula (I) ##STR1## wherein Cp represents a coupler residue; L and M each represents a nitrogen atom or a methine group, V represents a monocyclic or dicyclic aromatic ring of the benzene series, and at least one of L and M represnts a nitrogen atom; which releases a triazole derivative or a diazole derivative on coupling with an oxidized primary aromatic amine developing agent, and with the emulsion layer unit containing the ICC coupler represented by the general formula (I) or another layer containing a hydroquinone derivative represented by the general formula (II) ##STR2## wherein A and A' each represents a hydrogen atom or a group capable of being eliminated by an alkali, and A' can combine with R to Q to form a ring; P, Q and R each represents a hydrogen atom, an alkyl group, an aryl group, an alkylthio group, an arylthio group, a hydroxy group, a halogen atom, an alkoxy group, an aryloxy group, a heterocyclic ring or an --S--Z group, and P and Q can combine to form a ring; and Z represents a heterocyclic ring residue substantially photographically inert in a bonded state; which releases imagewise depending upon the development a compound having a mercapto group and/or a coupler which releases a compound having a mercapto group on coupling with an oxidized primary aromatic amine developing agent. The multilayer color photographic light-sensitive material provides color images having improved color reproduction, sharpness and graininess.
