| titleOfInvention | Positive metal image-forming element and process |
| abstract | This invention relates to photographic processes for the formation of positive, metal, nonsilver halide photographic images and to photographic elements for carrying out these processes. A photographic element having a metal, e.g., silver, surface or a surface having thereon nonsilver halide nuclei, e.g., silver particles, and a photoreactive composition comprising a spectral sensitizing dye, a mercaptan and an Alpha , Beta unsaturated monomer, adsorbed to said surface or nuclei which inhibits the removal of said metal or nuclei by chemical solvents or bleaching agents is featured in the present process. Upon imagewise exposure of said element to light, the inhibiting effect of the photoreactive composition is destroyed; and subsequent treatment with a bleaching agent removes the exposed metal surface or nonsilver halide nuclei, resulting in the formation of a direct positive metal photographic image or an active site capable of physical development to a negative metal photographic image. |
