ABSTRACT:
A method of overcoating a conductive polymer support with an aqueous-based polymer coating comprises crosslinking the conductive polymer with hydrolyzed tetraethyl orthosilicate prior to overcoating. An electrophotographic element can be prepared by coating a support with a conductive layer comprising a conductive polymer crosslinked with hydrolyzed tetraethyl orthosilicate (polysilicic acid) and overcoating with an aqueous-based layer of an electrically insulating polymer containing a photoconductor.
