ABSTRACT:
A photographic material for the production of multicolor images by means of diffusion transfer of complexed silver halide which includes a support having thereon at least three differently spectrally sensitive silver halide emulsion layers that are each sensitive to light of a different additive primary color, associated with each silver halide emulsion layer a silver precipitating layer containing development nuclei and a different dye-releasing compound for producing a subtractive multicolor image, and optionally one or more non-light-sensitive, non dye-releasing water-permeable hydrophilic colloid interlayers. In this material for better color separation the layers are arranged in a special order including the juxtaposition of two of the emulsion layers or separation thereof by layers penetrated by complexed silver halide so that the emulsion layers act as barriers against cross-diffusion.
