Abstract
A process for the preparation of an electrically conductive coating material for use in electrophotography applications comprises subjecting an epoxy-functional silane to hydrolytic condensation in a mixed solvent of alcohol and water in the presence of silica. The hydrolyzed material is then heat cured to form a resin coating comprising (R.sup.1 SiO).sub.3/2 units, where R.sup.1 comprises epoxy-functional groups. The coating has superior optical homogeneity and electrical conductivity without being detrimental to the functionality required of electrophotographic photosensitive bodies.
