Photoreceptor overcoatings containing hydroxy functionalized aromatic diamine, hydroxy functionalized triarylamine and crosslinked acrylated polyamide

摘要

An electrophotographic imaging member includingP Pa supporting substrate coated withPPat least one photoconductive layer, andPP an overcoating layer, the overcoating layer including aPPa hydroxy functionalized aromatic diamine andPPa hydroxy functionalized triarylamine dissolved or molecularly dispersed inPPa 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,PPR is an alkylene group containing from 1 to 10 carbon atoms,PPbetween 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, andPPthe 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 to achieve a weight average molecular weight between about 5000 and about 100000,PPR and R.sub.1 are independently selected from the group consisting of alkylene units containing from 1 to 10 carbon atoms;PPbetween 1 and 99 percent of R. sub.3 and R.sub.4 are independently selected from the group consisting of ##STR4## 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,PP y is an integer between 1 and 10, andPPthe remainder of the R.sub. 3 and R. sub.4 groups are selected from the group consisting of --H, -- CH. sub.2 OH, --CH.sub.2 OCH.sub.3, and --CH.sub.2 OC(O)--C(X)═CH. sub.2. PP The overcoating layer is formed by coating. The electrophotographic imaging member may be imaged in a process.
