Photographic silver halide materials and process comprising a pyrazolotriazole coupler. |
| 摘要 |
<p>Novel pyrazolotriazole dye-forming couplers contain an aliphatic or aromatic aryl ballast group containing a combination of an ether group (-O-) that enables desired magenta hue and a carboxy group (-COOH) enabling increased coupler reactivity. These couplers are useful in photographic silver halide materials and processes.</p> |
