ABSTRACT:
Photographic diffusion transfer products of the integral negative-positive type adapted to the provision of a diffusion transfer image retained within a permanent laminate having at least one developed silver halide emulsion, and viewable through a transparent support against a reflecting background, are described. A light-reflecting layer, comprising a polymeric binder matrix, a light-reflecting pigment and a light-absorbing particulate carbon-based pigment material, is employed in such products for the provision of opacification to permit in-light development and for the provision of a layer against which the diffusion transfer image may be viewed.
