Process for preparing overcoated electrophotographic imaging members

Abstract From the Canadian patent

A process for forming an overcoated electrophotographic imaging member by applying a coating of a cross-linkable siloxanol-colloidal silica hybrid material on an electrophotographic imaging member and thereafter contacting the coating with a fugitive ammonia gas condensation catalyst until the siloxanol-colloidal silica hybrid material forms a cross-linked solid layer. The cross-linkable siloxanol-colloidal silica hybrid material may be prepared by hydrolyzing trifunctional organosilanes and stabilizing the hydrolyzed silanes with colloidal silica The electrophotographic imaging member may comprise inorganic or organic photoconductive components in one or more layers.
