Color photographic materials including magenta coupler, carbonamide compound and aniline or amine compound, and methods |
| 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 ballasted aniline or amine compound. The carbonamide compound and the aniline or amine compound reduce continued coupling of the pyrazolone magenta dye-forming coupler during the bleach step in a color photographic process without altering the advantageous color image properties provided by the two-equivalent pyrazolone magenta dye-forming coupler |
