Abstract
A process for the production of a photographic color image by the silver dye bleach process, using a photographic material which comprises, on a base, at least one light-sensitive silver halide emulsion layer, which can contain a diffusion-resistant bleachable image dye, and immediately above this layer, on the side facing the light source, a silver halide-free layer containing a diffusion-resistant, bleachable image dye. The process gives very sharp photographic color images.
