Photographic coupler compositions containing carbonamides and methods |
| abstract |
Photographic coupler compositions comprise a pyrazolotriazole magenta dye-forming coupler and a performance-improving amount of a carbonamide compound. Improved performance is indicated by increased photographic speed, improved light stability of the resulting magenta dye and/or desired hypsochromic hue shifts in the resulting magenta dye. Color photographic materials and methods employ the coupler compositions. |
