Relation Between DAR Coupler’s Structure and Property

doi:10.7517/j.issn.1674-0475.2004.04.306

Abstract

Abstract: 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.

Key words: DAR coupler, structure, mechanism, property
