ABSTRACT:
A silver halide color photographic light-sensitive material comprising a support having thereon a silver halide emulsion layer and a compound represented by the following general formula (I): ##STR1## wherein COUP represents a coupler residue capable of being subjected to a coupling reaction with an oxidation product of an aromatic primary amine developing agent; TIME represents a timing group which is released upon the coupling reaction and subsequently releases ##STR2## Z represents a monocyclic or condensed heterocyclic ring consisting of a nitrogen atom and a carbon atom; L represents a divalent linking group; R.sup.1 represents a hydrogen atom or an alkoxycarbonyl group; R.sup.2 represents a hydrogen atom, an alkyl group, an aryl group, a heterocyclic group, an acyl group, a sulfonyl group, an alkoxycarbonyl group, a carbamoyl group, a sulfamoyl group, a thioacyl group or a thiocarbamoyl group; R.sup.3 represents a hydrogen atom; R.sup.2 and R.sup.3 may be bonded each other to form a hydrazone structure; a part of L and R.sup.1 may be bonded each other to form a hydrazone structure; and n represents 0 or 1.
The silver halide color photographic light-sensitive material containing the compound capable of imagewise releasing a fogging agent represented by the general formula (I) is improved in stability during preservation and has a high contrast and sensitivity. A method of forming a color image using the silver halide color photographic light-sensitive material is also disclosed.
