ABSTRACT:
In a color photographic material comprising a plurality of light-sensitive and non light-sensitive layers including at least two red sensitive coupler-containing silver halide emulsion layers of different speed, at least two green sensitive coupler-containing silver halide emulsion layers of different speed and a blue sensitive coupler-containing silver halide emulsion layer as well as a yellow filter layer located closer to the support than the blue sensitive silver halide emulsion layer but further removed from the support than any of the red sensitive or green sensitive layers, the sensitivity of the cyan partial image is significantly improved if the more sensitive red sensitive together with the more sensitive green sensitive silver halide emulsion layer forms a comparatively more sensitive emulsion layer unit which is located further removed from the support than a corresponding comparatively less sensitive emulsion layer unit formed by the less sensitive green sensitive and the less sensitive red sensitive silver halide emulsion layer, and the uppermost silver halide emulsion layer within the comparatively less sensitive emulsion layer unit is sensitive to the same spectral region as the lowermost silver halide emulsion layer within the comparatively more sensitive emulsion layer unit.
