Abstract A multi-layer color photographic element comprising a support having a plurality of silver halide emulsion layers, at least one layer being a red-sensitive silver halide emulsion layer, containing a cyan-forming coupler, such as phenol derivatives and Alpha -naphthol derivatives which have an iodine or a bromine atom at the ''''para'''' position to the hydroxyl group. Greensensitive emulsion layers and blue-sensitive emulsion layers are generally used in combination with said red-sensitive layer. The order of application of said layers is of no importance, as long as the red-sensitive emulsion layer is separated from different emulsion layers by an intermediate layer containing silver halide grains of reduced photo-sensitivity. Specific examples of the cyan-forming coupler and acceptable silver halide materials are defined in the disclosure.
