Abstract

Abstract The present invention relates to a photographic support having a secondary diffuse-reflective surface, and a color photosensitive material comprising at least one silver halide emulsion layer formed on the secondary diffuse-reflective surface of a photographic support. A photographic support of the present invention provides an image having remarkably improved brightness, saturation, tone reproducibility in shadow areas and sharpness. A color photosensitive material of the present invention provides an image having remarkably improved brightness, saturation, tone reproducibility in shades and sharpness and also capable of rapid development.
