Abstract
Abstract A silver halide color photographic light-sensitive material containing at least one coupler having a ballast group represented by the following general formula (I): ##STR1## wherein X represents a halogen atom, an alkyl group, an aryl group, a heterocyclic group, a hydroxy group, an alkoxy group, an aryloxy group, an acylamino group, a sulfonamido group, a carbamoyl group, a sulfamoyl group, a ureido group, an alkoxycarbonyl group, an alkoxycarbonylamino group, a sulfonyl group, an alkylthio group, a cyano group, a nitro group or a carboxyl group, l represents an integer of 1 to 4, and m represents an integer of 1 or 2, with the proviso that when X represents a hydroxyl group, a substituent other than a hydroxy group is also present on the phenyl ring.
