ABSTRACT:
A combination in a color photographic silver halide element and process of at least one red-sensitive silver halide emulsion layer comprising a particular naphtholic cyan dye-forming coupler with at least one green-sensitive silver halide emulsion layer comprising a particular pyrazolo[3,2-c]-s-triazole coupler and at least one blue-sensitive silver halide emulsion layer comprising a particular pivaloylacetanilide yellow dye-forming coupler enables improved color saturation of dye images, better relation of speed to grain characteristics and reduced unwanted spectral absorption of dye images formed. This combination is particularly useful in color photographic silver halide materials and processes for forming improved reversal dye images.
