| titleOfInvention | Process for producing positive or negative dye images using high iodide silver halide emulsions |
| abstract | PROCESSES FOR PRODUCING POSITIVE OR NEGATIVE DYE IMAGES USING HIGH IODIDE SILVER HALIDE EMULSIONS Abstract of the Disclosure Processes are disclosed for producing dye images employing photographic elements which comprise a support and coated thereon, at least one radiation-sensitive color-forming layer unit. This layer unit includes a substan-tially uniform distribution of catalyst and a radiation-sensitive, high iodide silver halide emulsion. A first method for producing dye images after imagewise exposure of the photographic element comprises the steps of imagewise poisoning the catalyst with iodide ion by developing the silver iodide containing silver halide emulsion and there-after employing the remaining unpoisoned catalyst to permit a redox reaction between a peroxide oxidizing agent and a dye-image-generating reducing agent. In a preferred element the high iodide silver halide emulsion is comprised of multifaceted, radiation-receptive silver iodide crystals and silver chloride crystals forming epitaxial junctions with the silver iodide crystals. A dye image of opposite sense can be produced using the preferred element by the steps of poison-ing the catalyst; selectively developing the silver chloride portion of the silver halide emulsion; and amplifying the resulting silver image using the peroxy redox amplification reaction. |
