ABSTRACT:
A color photographic silver halide material having at least one silver halide emulsion layer which is cyan coupling and contains a red sensitizer, at least one magenta coupling silver halide emulsion layer containing a green sensitizer and at least one yellow coupling silver halide emulsion layer containing a blue sensitizer on a support, in which the at least one blue sensitive halide emulsion layer contains a further spectral sensitizer (gap sensitizer) whose sensitization maximum lies between the sensitization maxima of the red and green sensitive silver halide emulsion layer and/or the at least one red sensitive silver halide emulsion layer contains an additional spectral sensitizer (gap sensitizer) whose sensitization maximum lies between the sensitization maxima of the green sensitive and the blue sensitive silver halide emulsion layer is distinguished by an increased range of gradations in the region of the maximum densities and a markedly improved detail reproduction in the region of high densities.
