Color diffusion transfer element with benzenesulfonamide

A color diffusion transfer light-sensitive material, wherein the light-sensitive material is a color diffusion transfer film unit comprising (a) an image-receiving sheet comprising a neutralizing layer, a neutralization timing layer, an image-receiving layer and a peeling layer each provided in order on a support, (b) a light-sensitive sheet comprising at least one compound represented by Formula (I) and having at least one silver halide emulsion layer combined with at least one dye image-forming compound on a support having a light-shielding layer, and (c) an alkaline processing composition spread between the image-receiving sheet and the light-sensitive sheet:

• ##STR34## 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 where n is 2 or more, the plural X groups may be the same or different.
