【摘要】 释放显影促进剂的成色剂(DAR)对彩色感光材料向高感、微粒方面发展起了重要作用。本文合成了三支无色DAR成色剂,选用N,N’-双-(2-氯-5-正十二烷氧基羰基)苯基丙二酰胺为母体,以2,5-二巯基-1,3,4-噻二唑为吸附基团,分别采用2-甲酰基苯肼、2-乙酰基苯肼和2-三氟乙酰基苯肼为增强基团,研究了它们的合成方法,得到了无色DAR成色剂YKA、YKB、YKC。通过红外光谱、质谱、核磁共振~1H谱等测试方法对成色剂的中间体及目标产物进行了表征和确认。更多还原

【Abstract】 The improvement of the color photographic materials having higher photosensitivity and composed of smaller grains owes much to the development accelerator releasing couplers. With[5-mercapto-(1,3,4) thiadiazol-2-yl-thio]-acetic acid adopted as the adsorption group and formic acid 2-(4-amino-phenyl)-hydrazide,acetic acid 2-(4-amino-phenyl)-hydrazide and trifluoro-acetic acid 2-(4-amino-phenyl)-hydrazide as the strengthen groups respectively,three new colorless DAR(YKA,YKB,YKC) couplers were synthesized from N, N’-bis-(2-chloro-5-n-dodecyloxy-carbonyl) phenylmalonamide The intermediates and the target compound were characterized and confirmed by means of IR,MS,~1HNMS.更多还原
