摘要
以黄成色剂为母体,环状酰肼为显影促进基团,分别以6-氨基苯并咪唑和苯基巯基三氮唑为吸附基团,合成了2种新型DAR成色剂,产率分别为60.8%和48.2%。其结构经IR、1HNMR、MS和元素分析测试技术得到确证。实验结果表明,合成的DAR成色剂在提高感光度时不会增大灰雾密度。
Two novel DAR yellow couplers in which there is cyclic acylphenylhydrazine as the development accelerating group, and 6-aminobenzimidazole or phenyhhiohriogenazole as the adsorption group were synthesized, and the yield was 60. 8% and 48.2% respectively. The structures were confirmed by IR, ^1H NMR, MS and elemental analysis. In practical application, the photosensitivity was increased but the fog was not increased.
