  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。

  The present invention relates to a method for preparing an emulsifiable solid agrochemical composition which contains an inorganic salt and which can be used as an agrochemical emulsion. The preparation method according to the present invention has the advantage that, because there is no need for a step of heating and evaporating a solvent or water, it is possible to use a surfactant or active ingredient that has a low boiling point or breaks down drastically at a high temperature, and, due to the solid-phase form, it is possible to minimize the amount that sticks to a container as there is no need to use a special synthetic resin or glass bottle that entails high packaging costs. Also, a granular emulsifier (EG) or a powdery emulsifier (EP) produced by means of the method according to the present invention can be further diluted in water before use so as to form common emulsion (EC) emulsified particles (0.1 µm to 100 µm) to transparent microemulsion particles (0.001 µm to 1 µm or 1 nm to 1000 nm), and thus the emulsion size can be freely modified so as to maximise the activity of the agrochemical component in accordance with the characteristics of a crop or an insect pest.

  本发明涉及一种可乳化的固体农用化学品组合物的制备方法，该组合物含有一种无机盐，可用作农用化学品乳剂。根据本发明的制备方法具有以下优点：由于不需要加热和蒸发溶剂或水的步骤，因此可以使用低沸点或在高温下急剧分解的表面活性剂或活性成分；由于是固相形式，因此可以最大限度地减少粘附在容器上的量，因为不需要使用需要高昂包装成本的特殊合成树脂或玻璃瓶。此外，根据本发明的方法生产的颗粒状乳化剂（EG）或粉末状乳化剂（EP）在使用前可进一步用水稀释，以形成普通乳液（EC）乳化颗粒（0.1 微米至 100 微米）到透明微乳液颗粒（0.001 微米至 1 微米或 1 纳米至 1000 纳米），因此可根据作物或害虫的特性自由改变乳液大小，以最大限度地提高农用化学品成分的活性。
