| titleOfInvention | Photographic process and composition employing CO(III) complexes and silver halide solvents |
| abstract | A photographic process is provided wherein a photographic element comprising a support having thereon imagewise-exposed photosensitive metal salt is contacted with an alkaline processing solution to form a first image comprising metal, a second photographic image is formed, and the metal image and the photosensitive metal salt are bleached and fixed, while the element is contacted with said alkaline processing solution, with the combination of (1) a cobalt(III) complex and (2) a solvent for said photosensitive metal salt. In another aspect of the invention, metallic images are amplified by treatment with an alkaline processing solution to contact the metallic image with color-developing agent and cobalt(III) complex to produce oxidized color-developing agent, reacting the color-developing agent with a photographic color coupler to form dye, and adding to the combination of developing agent and cobalt(III) complex sufficient silver halide solvent to bleach and fix the element after the metallic image has been amplified by the dye. Novel processing solutions are also provided which comprise aromatic primary amino color-developing agent, a silver halide solvent and a cobalt(III) complex. |
