摘要： Color photographic elements containing silver halide and incorporated colored and color-forming materials are described. These elements have (a) a layer containing a yellow dye or yellow dye precursor that is bleachable by a mild silver-dye-bleach procedure and (b) at least one other layer, spectrally sensitized to green light, which contains a color-forming coupler which forms magenta dye upon reaction with oxidized color developer. Such elements, when they are processed by a process have improved graininess and yield sharper images. The novel process comprises the steps:A. develop in black and white developer,B. apply non-fixing silver-dye-bleach solution,C. rinse,D. fog and color developE. washF. bleach and fix.A "positive" colored image results.

摘要： A novel class of redox releasing compounds contains an N,N-disubstituted carbamoyl ballast group. These compounds can be used in photographic elements and processes to release a dye or other photographically useful group as a function of silver halide development.
