含海因环二当量黄成色剂的合成
Synthesis of Two-equivalent Yellow Couplers
-
摘要: 合成了3种苯甲酰乙酰替苯胺型二当量黄成色剂,其结构经元素分析、核磁共振、熔点等手段得到了确证,应用结果表明3种二当量黄成色剂与目前国内所用CP116相比具有较高的活性和较好的照相性能。Abstract: Three two equivalent yellow couplers were synthesized. They have been identified by elementary analysis, 1H NMR and melting point determination. Applied tests showed that the class of two equivalent couplers had good color developing properties.
