在卤化银感光材料的制造和加工过程中需要应用多种有机化合物,以改善感光材料的照相性能(例如增加感光度,扩大感色范围,降低灰雾等)、物理机械性能(例如增加塑性、提高涂层耐磨损强度等)、提高感光材料的涂布质量、消除气泡、条道等弊病,以及改善感光材料冲洗加工性能(例如加速显影过程,加强定影和漂白能力等)。这些有机化合物统称为照相有机物。
A variety of organic compounds are required in the manufacture and processing of silver halide light-sensitive materials to improve photographic properties of the light-sensitive materials (eg, increase sensitivity, increase color range, reduce fogging, etc.), physical mechanical properties (eg, increase in plasticity, Improve the abrasion resistance of the coating, etc.), improve the coating quality of the photosensitive material, eliminate the defects such as air bubbles and streaks, and improve the processing performance of the photosensitive material (such as accelerating the developing process, strengthening the fixing and bleaching ability, etc.). These organic compounds are collectively referred to as photographic organics.
