摘要：通过分析DAR成色剂的结构和作用机理,讨论了其结构与照相性能之间的关系.DAR成色剂的结构可表示为:Cp—L—A,其中Cp代表成色剂母体,A代表促进显影的功能基团即增强基团,L代表连接基团同时也有吸附功能即吸附基团.本文指出:当吸附基团和增强基团相同时,母体对照相性能影响不大;当母体及增强基团相同时,吸附基团的吸附性越强,照相性能越好;当母体及吸附基团相同时,增强基团的感染显影作用越强,照相性能越好.
The relation of the structure of DAR coupler and it's photographic property was reported by analysizing the structure of DAR coupler.The structure of DAR coupler can be represented by Cp-L-A.Cp is the coupler residue;L is the divalent linking group also is the adsorbing group;A is the development accelerating functional group.In this paper,conclusion were made:the Cp can make no effect apparently on photographic property when L and A are the same.The stronger of the development accelerating functional group,the better of the DAR coupler's photographic property when Cp and L are the same.The stronger of the adsorbability of adsorbing group,the better of the DAR coupler's photographic property when Cp and A are the same.
