摘要： A multi-layer color photographic recording material having at least one photosensitive silver halide emulsion layer containing a color coupler contains in at least one photosensitive silver halide emulsion layer a non-diffusing, 2-equivalent color coupler which, under chromogenic development conditions, by coupling with a color developer oxidation product, releases a photographically inert ballast group from the coupling site and so forms a dye removable by rinsing which makes no contribution to color density. In a preferred embodiment of the invention, the non-diffusing, 2-equivalent color coupler which, under chromogenic development conditions, by coupling with a color developer oxidation product, releases a photographically inert ballast group from the coupling site and so forms a dye removable by rinsing which makes no contribution to color density, is a cyan coupler, for example a naphtholic or phenolic coupler, which is preferably located in the most highly sensitive sub-layer of a green-sensitive silver halide emulsion layer unit consisting of two or more sub-layers. The material exhibits an improved sensitivity/grain or gradation/grain relationship.
