Abstract

Abstract A color photographic light-sensitive material comprising, on a reflective support, at least one light-sensitive silver halide emulsion layer containing a dye-forming coupler and a non-light-sensitive layer provided on the light-sensitive silver halide emulsion layer, located furthest from the reflective support, the non-light-sensitive layer containing: (a) a benzotriazole derivative represented by the following formula (I): ##STR1## wherein R 1 and R 2 independently represent an alkyl, an alkoxy, an alkenyl, each alkyl, alkoxy, or alkenyl having not less than 4 carbon atoms, an aryl, or an aryloxy, said aryl and aryloxy each being substituted or unsubstituted and wherein R 3 represents hydrogen, a halogen, an alkyl, an alkoxy, an alkenyl, each alkyl, alkoxy, or alkenyl having not less than 4 carbon atoms, an aryl, or an aryloxy; and (b) at least one compound having selected from the formulae (II) or (III): ##STR2## wherein R 4 and R 5 independently represent an alkyl, having not less than 5 carbon atoms, an aryl, or an aralkyl, said aryl and aryloxy each being substituted or unsubstituted; ##STR3## wherein R 6 , R 7 and R 8 independently represent an alkyl having not less than 5 carbon atoms.
