Abstract

A negatively developing color photographic silver halide material having a support and at least one blue-sensitive silver halide emulsion layer containing at least one yellow coupler, at least one green-sensitive silver halide emulsion layer containing at least one magenta coupler and at least one red-sensitive silver halide emulsion layer containing at least one cyan coupler, at least 95 mol % of the silver halides of which consist of AgCl, and in which at least one silver halide emulsion layer exhibits solarization on analogue exposure, is distinguished on scanning exposure by elevated color density and on analogue exposure by contrast which is independent of exposure time.
