An electrophotographic imaging member including a supporting substrate coated with at least one photoconductive layer, and an overcoating layer, the overcoating layer including a a hydroxy functionalized aromatic diamine and a hydroxy functionalized triarylamine dissolved or molecularly dispersed in a crosslinked acrylated polyamide matrix, the hydroxy functionalized triarylamine being a compound different from the polyhydroxy functionalized aromatic diamine, the crosslinked polyamide prior to crosslinking being selected from the group consisting of materials represented by the following Formulae I and II: wherein: n is a positive integer sufficient to achieve a weight average molecular weight between about 5000 and about 100,000, R is an alkylene group containing from 1 to 10 carbon atoms, between 1 and 99 percent of the R2 sites are wherein X is selected from the group consisting of -H (acrylate), -CH3(methacrylate), alkyl and aryl, and the remainder of the R2 sites are selected from the group consisting of -H, -CH2OCH3, and -CH2OH, and wherein: m is a positive integer sufficient to achieve a weight average molecular weight between about 5000 and about 100000, R and R1 are independently selected from the group consisting of alkylene units containing from 1 to 10 carbon atoms; between 1 and 99 percent of R3 and R4 are independently selected from the group consisting of wherein X is selected from the group consisting of hydrogen, alkyl, aryl and alkylaryl, wherein the alkyl groups contain 1 to 10 carbon atoms and the aryl groups contain 1 to 3 alkyl groups, y is an integer between 1 and 10, and the remainder of the R3 and R4 groups are selected from the group consisting of -H, -CH2OH, -CH2OCH3, and -CH2OC(O)-C(X)=CH2. The overcoating layer is formed by coating. The electrophotographic imaging member may be imaged in a process. |
