ABSTRACT:
A colour photographic recording material, comprising of a transparent film base, red-sensitive, green-sensitive and blue-sensitive silver halide emulsion layer units which are disposed thereon and which contain colour couplers, and optionally of further light-insensitive layers, wherein the green-sensitive silver halide emulsion layer unit comprises at least two green-sensitive partial layers, the partial layer of which which is furthest from the film base has the highest sensitivity and is situated further from the film base than is each partial layer of the red-sensitive silver halide emulsion layer unit, and wherein each partial layer of the blue-sensitive silver halide emulsion layer unit is situated further from the film base than is the highest-sensitivity partial layer of the green-sensitive silver halide emulsion layer unit, contains, in the highest-sensitivity partial layer of the green-sensitive silver halide emulsion layer unit, an organic yellow dye which can be decolorised during processing; the light-insensitive binder layer adjacent thereto on the side remote from the film base contains no silver halide development nuclei and contains substantially no dye which can be decolorised during processing.
