Abstract

A color photographic recording material with a reflective support which contains a spectrally sensitized silver halide emulsion containing at least one sensitizer for the spectral region B in a layer free from color coupler adjacent at least one dye-producing silver halide emulsion layer sensitized for the spectral region A, the sensitivity of the spectrally sensitized silver halide emulsion of the layer free from color coupler being lower by 0.6 to 2.5 log H units than the sensitivity of the sensitized silver halide emulsion of the dye-producing silver halide emulsion layer, is distinguished by an extended gradation range in the region of the maximum densities and, hence, by distinctly improved fine detail resolution at high densities.
