ABSTRACT:
A silver halide color light-sensitive material including a support having thereon at least one hydrophilic colloidal layer is disclosed, wherein the hydrophilic colloidal layer contains a DIR coupler represented by formula (I): ##STR1## wherein R.sup.1 represents a hydrogen atom, an aliphatic group, an aromatic group, or a heterocyclic group; R.sup.2 represents an organic group; X and Y each represent --N.dbd. or ##STR2## wherein R.sup.3 represents a hydrogen atom, a halogen atom, a cyano group, a nitro group, an amino group, an acyl group, an acylamino group, a carbamoyl group, a carbamoylamino group, a sulfonyl group, a sulfonylamino group, a sulfamoyl group, a sulfamoylamino group, an alkoxy group, an aryloxy group, an alkoxycarbonyl group, an aryloxycarbonyl group, a hydroxyl group, a sulfenyl group, a sulfinyl group, an aliphatic group, an aromatic group, or a heterocyclic group; and Z represents a releasable group which is released on reacting with an oxidation product of an aromatic primary amine developing agent to become a development inhibitor or a precursor thereof and which diffuses into a color developing solution and then decomposes to a compound having no substantial influence on photographic properties.
