Abstract

Abstract A color photographic light-sensitive material comprising a reflective support having thereon a plurality of silver halide emulsion layers of which the emulsion layer located farthest from said support has, on each of both the support side thereof and the uppermost side at least one nonlight-sensitive layer containing an effective amount of an ultraviolet absorbing agent, said ultraviolet absorbing agent being used in said nonlight-sensitive layer on the uppermost side of said emulsion layer being a 2-(2'-hydroxyphenyl)benzotriazole-type compound which is in the liquid form at normal room temperature.
