Abstract (en)
[origin: EP0607800A1] A colour-photographic silver-halide material having at least one cyan-coupling silver-halide emulsion layer containing a red sensitiser, at least one magenta-coupling silver-halide emulsion layer containing a green sensitiser and at least one yellow-coupling silver-halide emulsion layer containing a blue sensitiser on a support (carrier, base), in which a silver-halide emulsion which has been sensitised by means of a further spectral sensitiser (gap sensitiser) and whose sensitivity maximum is between the sensitivity maxima of the red-and green-sensitive or the green-and blue-sensitive silver-halide emulsion layers, is provided in at least one colour coupler-free layer, is distinguished by an extended gradation range in the region of the maximum densities and significantly proved definition in the region of high densities.
