Abstract
Abstract There is disclosed a photosensitive silver halide color photographic material comprising a support having on one side thereof, an antihalation layer, a red-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer and a blue-sensitive silver halide emulsion layer wherein each of said silver halide emulsion layers contains a non-diffusable coupler. The other surface of the support has thereon a dye-containing backing layer. The antihalation layer contains no more than 0.2 g/m2 of silver and the total amount of silver contained in the silver halide emulsion layers is at least 7.0 g/m2.
