| 摘要 |
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 first photosensitive silver halide layer having associated therewith a diffusion transfer process dye image-forming material; a second photosensitive silver halide layer; 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 adjacent second transparent dimensionally stable layer; and to specified photographic diffusion transfer color processes employing such products.
