ABSTRACT:
A color photographic recording material having at least one silver halide emulsion layer unit containing color coupler, which unit comprises at least two adjacent silver halide emulsion partial layers of the spectral sensitivity concerned, one of which is more sensitive and one less sensitive, contains in a reactive association with at least one more sensitive silver halide emulsion partial layer having a comparatively low color coupler content relative to the silver halide content, a compound (or a precursor compound thereof), which is capable under chromogenic development conditions of forming a substantially colorless, diffusible coupling product with the color developer oxidation product, which coupling product is capable under chromogenic development conditions in the presence of an oxidising agent of forming a dye with a color coupler, with transfer of the residue originating from the color developer.
On chromogenic development, color images having improved grain are obtained.
