A silver halide photosensitive material is developed with a developing solution containing an aromatic amine in the presence of a coupler of the general formula:
wherein R1, R2 and R3 each represents a hydrogen atom or a substituent group, and X represents a hydrogen atom or a coupling eliminable group; 46 specific couplers are shown, and four synthesis methods. An aromatic color stabilizer may be present. Magenta color image of high color purity is formed.
用含有芳香胺的显影液在通式如下的耦合剂存在下对卤化银感光材料进行显影:
其中 R1、R2 和 R3 各代表一个氢原子或一个取代基团,X 代表一个氢原子或一个可消除偶联的基团;共显示了 46 种特定的偶联剂和四种合成方法。可能存在芳香族颜色稳定剂。形成高色纯度的品红色图像。
