ABSTRACT:
Using a color photographic negative recording material which contains a most sensitive, a medium-sensitive and a least sensitive silver halide part layer for recording light from at least one of the spectral ranges of red, green and blue, at least one of the two more sensitive part layers containing a DIR coupler and the most sensitive partial layer and the least sensitive part layer containing a color coupler which couples faster than the color coupler in the medium-sensitive part layer by a factor of at least 1.5, the sharpness can be improved without impairing the color grain.
