ABSTRACT:
Disclosed is a color photographic material having, on a reflective support coated with waterproof resin layers, at least three different color-sensitive silver halide emulsion layers containing any of cyan, magenta and yellow couplers, in which the number of said waterproof resin layers under said photographic constitutive layers is at least three, at least one of said waterproof resin layers contains from 15% by weight to 45% by weight of a white pigment, the waterproof resin layer nearest to the substrate of the support and that nearest to the photographic constitutive layers donor contain a white pigment or contain it in an amount of 20% by weight or less, the thickness of the waterproof resin layer nearest to the photographic constitutive layers is 5 .mu.m or less, and at least one emulsion layer contains high silver chloride emulsion grains having a silver chloride content of 95 mol % or more and contains a mercaptohetercyclic compound. The photographic material can be processed rapidly to form a color image having high sharpness while having high whiteness in the background area. The material has high folding resistance, and the density of the image at the folded part is not lowered. Even when the material is cut with a dull cutter, the edges of the resulting pieces are not rough. The edges of the pieces are not colored by development.
