Abstract of the Disclosure The present invention relates to photography, particularly, to photographic products specifically adapted for employment in specified photographic diffusion transfer color processes and, more particularly, to photographic products which comprise a fixed or permanent composite photosensitive structure including, as essential layers, in sequence, a first dimensionally stable layer transparent to actinic radiation; a polymeric layer dyeable by a diffusion transfer process dye image-forming material; a processing composition permeable opaque layer; a photo- sensitive silver halide layer having associated therewith a diffusion transfer process dye image-forming material; a processing composition permeable layer impermeable to a diffusion transfer process dye image-forming material; a second dimensionally stable layer transparent to actinic radiation; and means for providing a diffusion transfer process processing composition preferably retaining opacifying agent intermediate the dye image-forming material impermeable polymeric layer and the next adja- cent second transparent dimensionally stable layer; and to specified photographic diffusion transfer color processes employing such products.
