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:

Hybrid color photographic elements and processes for developing same

Color photographic elements containing silver halide and incorporated color-forming materials are described. These elements contain at least two differentially light-sensitive emulsion layers, the overlying layer being sensitive to the relatively shorter wavelengths and containing at least one yellow dye-forming color coupler which has the unusual ability to inhibit the reaction of competing couplers (such as citrazinic acid, for example) when competing couplers are used in color developing solutions in the conventional manner. Use of these couplers in the overlying (color) layer of multi-layer color photographic elements makes it possible to produce colored images having improved graininess. Couplers having this unusual capability are selected from those having the structures: ##SPC1## Wherein R.sub.1, R.sub.2 and R.sub.3 are as defined herein.
