Abstract

A light-sensitive color photographic material comprises four silver halide emulsion layer units, one for recording each of the yellow, magenta and cyan partial images and one which serves as a color correction layer. The latter mentioned silver halide emulsion layer is fogged, has a lower light-sensitivity than the light-sensitive partial image recording layer, and contains color couplers for producing a yellow to magenta masking image to compensate for the undesired side densities in at least two image recording layers.
