成色剂的类别和应用特点现代彩色多层感光材料应用减色法原理形成彩色影象。在每一个乳剂层中成色剂与显影剂氧化物分别生成黄、品红和青等三补色。根据成色剂所能形成的颜色不同,在化学结构上把它分为三种类型,即黄、品红和青成色剂(实例见表2、表3和表4) 。人们对彩色感光材料在清晰度、颗粒性、彩色还原、影象色牢度等质量特性方面不断提出的改进要求,促进了成色剂的研制工作。在 Types and Applications of Couplings Modern color multi-layered photographic materials form color images using subtractive colorimetry. The coupler and developer oxide in each emulsion layer generate three complementary colors of yellow, magenta, and cyan, respectively. Depending on the color that the couplers can form, they are divided in chemical structure into three types: yellow, magenta, and cyan couplers (see Tables 2, 3, and 4 for examples). People’s color photosensitive material in the clarity, granularity, color reproduction, color fastness and other quality characteristics of the continuous improvement requirements, and promote the development of coupler. in
