摘要:
A color photographic silver halide material having at least two blue-sensitive, yellow coupler containing silver halide emulsion layers, at least two green-sensitive, magenta coupler containing silver halide emulsion layers and at least two red-sensitive, cyan coupler containing silver halide emulsion layers together with conventional interlayers and protective layers, wherein photosensitive layers of identical color sensitivity differ with regard to the photographic sensitivity thereof and the more highly sensitive layers are arranged further away from the support than the less sensitive layers of identical color sensitivity, which material contains, in a layer which is arranged further from the support than the most highly sensitive, blue-sensitive layer, both at least one yellow coupler and at least one magenta or cyan coupler, is distinguished by improved grain and sensitivity combined with very good color reproduction.
