摘要:
A color photographic material comprising at least one cyan-coupling silver halide emulsion layer containing 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 a silver halide emulsion is provided in a coupler-free layer sensitized with another spectral sensitizer (a gap sensitizer) of which the sensitization maximum lies between the sensitization maxima of the red- and green-sensitive layers or the green- and blue-sensitive layers, is distinguished by an extended gradation range towards the maximum densities and by distinctly improved detail reproduction in the region of high densities.
