Abstract
A color photographic silver halide material which is developed as a negative, at least 90 mol % of the silver halides of which consist of AgCl, and which contains a compound of formula (I) or formula (II) in a light-insensitive layer which is further from the support than is each light—light sensitive layer, is distinguished by its improved color reproduction.
Claims7
A color photographic silver halide material which is developed as a negative, which comprises at least 90 mol % of the silver halides of which consists of AgCl, which contains 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, a light-insensitive layer, which is further from the support than each of the light-sensitive layers, contains a compound of formula (II)
