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

An electrophotographic imaging process comprising

• providing an electrophotographic imaging member comprising a supporting substrate coated with at least a charge generating layer, a charge transport layer and an overcoating layer, the overcoating layer a comprising a hydroxy functionalized aromatic diamine and a hydroxy functionalized triarylamine dissolved or molecularly dispersed in a crosslinked acrylated polyamide matrix and any hydrogen bonding product of the hydroxy functionalized aromatic diamine, hydroxy functionalized triarylamine and crosslinked acrylated polyamide matrix,
• uniformly charging the imaging member,
• exposing the imaging member with activating radiation in image configuration to form an electrostatic latent image,
• developing the latent image with toner particles to form a toner image, and
• transferring the toner image to a receiving member.

An electrophotographic imaging member comprising a supporting substrate coated with at least one photoconductive layer and an overcoating layer, the overcoating layer formed from a mixture comprising

• 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:
• ##STR45## 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 R.sub.2 sites are ##STR46## wherein X is selected from the group consisting of --H, --CH.sub.3, alkyl and aryl, and

• R and R.sub.1 are independently selected from the group consisting of alkylene units containing from 1 to 10 carbon atoms,
• between 1 and 99 percent of R.sub.3 and R.sub.4 are independently selected from the group consisting of ##STR48## 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 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).dbd.CH.sub.2.
