摘要
本文合成了两个新型DAR成色剂,其结构经IR,1H-NMR和MS得到确证.照相性能试验结果表明:DAR成色剂D1能提高感光度20%,而DAR成色剂D2在目前的显影条件下没有提高感光度的作用.通过分析其结构,找到了结构与照相性能之间的关系.
Two novel DAR couplers were synthesized in this paper, the structures were confirmed by elemental analysis, IR, MS, and ^1H-NMR. It was found that D1 could increase sensitivity by 20 %, but D2 could not increase sensitivity by the research of it＇s photographic properties.
