ABSTRACT:
Color photographic materials comprise a support bearing a silver halide emulsion and a coupler composition. The coupler composition comprises a two-equivalent pyrazolone magenta dye-forming coupler, a ballasted carbonamide compound, and a developer inhibitor-releasing coupler. The carbonamide compound reduces continued coupling of the pyrazolone magenta dye-forming coupler during the bleach step in a color photographic process without altering the advantageous properties provided by the combination of the two-equivalent pyrazolone magenta dye-forming coupler and the developer inhibitor-releasing coupler.
