Abstract
A color photographic light-sensitive material has excellent smoothness and glossiness on the surface of the light-sensitive material and provides good color developing performance and excellent color reproduction performance as well as less pressure fog in aging and storage. The light-sensitive material comprises a reflective support having provided thereon at least one yellow dye forming coupler-containing silver halide emulsion layer, at least one magenta dye forming coupler-containing silver halide emulsion layer, and at least one cyan dye forming coupler-containing silver halide emulsion layer, each having a different light sensitivity, wherein the reflective support comprises a substrate having provided at least on the surface of an emulsion layer-coated side thereof, a composition prepared by mixing and dispersing a white pigment in a resin containing polyester as a main component; the cyan dye forming coupler-containing silver halide emulsion layer contains at least one cyan dye forming coupler compound represented by the following formula (Ia); and the film pH of the light-sensitive material is 4.0 to 6.5: ##STR1## wherein R.sub.1 and R.sub.2 each represents an electron attractive group having a Hammett's substituent constant .sigma..sub.p of 0.20 or more, provided that the sum of the .sigma..sub.p values of R.sub.1 and R.sub.2 is 0.65 or more, and Za, Zb, Zc, and X are as defined in the specification.
