Abstract

An electrophotographic imaging member including PA1 a supporting substrate coated with PA1 at least one photoconductive layer, and PA1 an overcoating layer, the overcoating layer including a PA2 a hydroxy functionalized aromatic diamine and PA2 a hydroxy functionalized triarylamine dissolved or molecularly dispersed in PA2 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: ##STR1## wherein: n is a positive integer sufficient to achieve a weight average molecular weight between about 5000 and about 100,000, PA1 R is an alkylene group containing from 1 to 10 carbon atoms, PA1 between 1 and 99 percent of the R.sub.2 sites are ##STR2## wherein X is selected from the group consisting of --H (acrylate), --CH.sub.3 (methacrylate), alkyl and aryl, and PA1 the remainder of the R.sub.2 sites are selected from the group consisting of --H, --CH.sub.2 OCH.sub.3, and --CH.sub.2 OH, and ##STR3## wherein: m is a positive integer sufficient …
