| abstract |
A light-sensitive composition is disclosed, containing at least one of tetrakisazo compounds having the following general formula [1]: <IMAGE> [1] wherein Cp represents a coupler residue; A is a single bond, <IMAGE> in which n is an integer of from 1 to 3, or a divalent aromatic organic residue, and B1 and B2 each represents a hydrogen atom or an electron attractive group; Z represents <IMAGE> -O-, -S- or -Se-, in which R6 represents a hydrogen atom, a substituted or unsubstituted lower alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted alkoxycarbonyl group, a substituted or unsubstituted aryloxycarbonyl group or a substituted or unsubstituted acyl group; and Ar represents a substituted or unsubstituted divalent aromatic carbon ring group, or a substituted or unsubstituted divalent heterocyclic aromatic ring group. An electrophotographic light-sensitive material is also disclosed, comprising an electrically conductive support and a layer containing an electric charge carrier transporting compound and the tetrakisazo compound as an electric charge carrier generating compound. An electrophotographic light-sensitive material is further disclosed, comprising an electrically conductive support, an electric charge carrier transporting layer containing an electric charge carrier transporting compound, and an electric charge carrier generating layer containing the tetrakisazo compound. |
