Overcoated photoreceptors and methods of using overcoated photoreceptors

摘要

An electrophotographic imaging member including a supporting substrate coated with at least photoconductive layer, a charge transport layer and an overcoating layer, the overcoating layer including a hydroxy functionalized aromatic diamine and a hydroxy functionalized triarylamine dissolved or molecularly dispersed in a crosslinked polyamide matrix, 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 unit containing from 1 to 10 carbon atoms, between 1 and 99 percent of the R2 sites are -H, and the remainder of the R2 sites are -CH2-O-CH3, and wherein: m is a positive integer sufficient to achieve a weight average molecular weight between about 5000 and about 100000, R1 and R are independently selected from the group consisting of alkylene units containing from 1 to 10 carbon atoms, and between 1 and 99 percent of the R3 and R4 sites are -H, and the remainder of the R3 and R4 sites are -CH2-O-CH3. Coating compositions for the overcoating layer of this invention as well as methods of making and using the overcoated photoreceptor are also disclosed.
