Abstract

A color photographic film having a support, 2 or 3 red-sensitive, cyan-coupling silver halide emulsion layers, 2 or 3 green-sensitive, magenta-coupling silver halide emulsion layers, 2 or 3 blue-sensitive, yellow-coupling silver halide emulsion layers, conventional interlayers and protective layers together with a yellow filter layer arranged closer to the support than the blue-sensitive layers, wherein at least one green-sensitive silver halide emulsion layer is arranged further away from the support than all the other photosensitive layers, exhibits improved sharpness without color distortion if at least 50% of the projected surface area of the silver halide emulsion of the green-sensitive silver halide emulsion layer, of which there is at least one, consists of tabular silver halide grains having an aspect ratio of at least 3.
