METHOD OF PREPARING PHOTOGRAPHIC SILVER HALIDE EMULSIONS |
摘要 |
<p>Silver halide emulsions are prepared by silver halide precipitation in the presence of a reducing agent, physical ripening and, if desired, chemical ripening wherein subsequent to the addition of reducing agent and before the grains have reached their final size an oxidizing agent is added to the emulsion. By means of the reducing and oxidizing agents, the gradation and photosensitivity characteristics of the emulsion can be controlled at will.</p> |
