ABSTRACT:
A process for forming an overcoated electrophotographic imaging member comprising applying on an electrophotographic imaging member a coating in liquid form comprising a cross-linkable siloxanol-colloidal silica hybrid material having at least one silicon bonded hydroxyl group per every three --SiO-- units and a catalyst for the cross-linkable siloxanol-colloidal silica hybrid material, the coating in liquid form having an acid number less than about 1 and curing the cross-linkable siloxanol-colloidal silica hybrid material until the siloxanol-colloidal silica hybrid material forms a hard cross-linked solid organosiloxane-silica hybrid polymer layer.
