Abstract

A color photographic silver halide material which contains as photosensitive layers on a support at least one red-sensitive silver halide emulsion layer containing at least one cyan coupler, at least one green-sensitive silver halide emulsion layer containing at least one magenta coupler and at least one blue-sensitive silver halide emulsion layer containing at least one yellow coupler, in which, above a photosensitive layer (seen from the support outwards), at least one further layer is provided which contains a colorless compound or combination of colorless compounds, which under processing conditions after exposure gives rise to a uniform, slight color density of a predetermined color and predetermined density over the entire surface, allows correction of the print densities without sensitivity being reduced.
