ABSTRACT:
There is disclosed a color diffusion transfer light-sensitive material in which a transferred density is increased and a processing temperature dependency of the transferred density is improved to a large extent. The above light-sensitive material comprises a color diffusion transfer light-sensitive element containing at least one of the compounds represented by the following Formula (I), and an alkali processing composition: ##STR1## wherein R.sup.1 represents an alkyl group; X represents an alkyl group, a cycloalkyl group, an aryl group, an alkoxy group, an aryloxy group, an acylamino group, a sulfonylamino group, a ureido group, an alkylthio group, an arylthio group, an alkoxycarbonyl group, a carbamoyl group, a sulfamoyl group, a sulfonyl group, an alkoxycarbonylamino group, an amino group, a sulfamoylamino group, a cyano group, a hydroxyl group, or a halogen atom; n represents an integer of 1 to 4; and when n is 2 or more, a plurality of X may be the same or different.
