A silver halide color photographic light-sensitive material comprising a support having thereon at least one silver halide emulsion layer, the color photographic light-sensitive material containing a coupler which releases a compound after the coupling reaction with the oxidation product of a developing agent, the released compound being capable of releasing further a photographically useful group by an oxidation-reduction reaction with the oxidation product of another developing agent. The compound used in the present invention is chemically stable and can release a photographically useful group under control; therefore the silver halide color photographic light-sensitive material containing the compound has good stability during storage and high sensitivity and provides a color image having good image qualities such as sharpness, graininess, color reproducibility, etc.
一种卤化
银彩色感光材料,包括一个支撑体,支撑体上至少有一层卤化
银乳剂层,该彩色感光材料含有一种耦合剂,该耦合剂在与一种显影剂的氧化产物发生耦合反应后释放出一种化合物,释放出的化合物能够通过与另一种显影剂的氧化产物发生氧化还原反应进一步释放出一种对照片有用的基团。本发明中使用的化合物
化学性质稳定,可在控制下释放出对照片有用的基团;因此,含有该化合物的卤化
银彩色感光材料在储存期间具有良好的稳定性和较高的感光度,可提供具有良好图像质量(如锐度、颗粒感、色彩再现性等)的彩色图像。
