ABSTRACT:
A color photographic silver halide material having at least two red-sensitive, cyan-coupling silver halide emulsion layers of different photographic sensitivity, at least two green-sensitive, magenta-coupling silver halide emulsion layers of different photographic sensitivity and at least one blue-sensitive, yellow-coupling silver halide emulsion layer, and having intermediate layers at least between silver halide emulsion layers of different color sensitivity, wherein at least one color coupler is provided in an intermediate layer which is directly adjacent to a lowest-sensitivity silver halide emulsion layer which is sensitive to a defined spectral region and which couples to the complementary color, which color coupler couples in a non-complementary manner with respect to the aforementioned lowest-sensitivity silver halide emulsion layer, is distinguished by its improved reproduction of yellow color shades.
