Zusammenfassung:An improved overcoat layer for an organic photoconductor drum of an electrophotographic image forming device is provided. The overcoat layer is prepared from a curable composition including a crosslinkable siloxane, an acrylic polymer with pigment affinic groups, nano metal oxide particles sized less than 400 nm in combination with a urethane acrylate resin having at least 6 functional groups. The outermost layer of an organic photoconductors is coated with the overcoat formulation of the present invention then cured. The resulting cured overcoated organic photoconductor has improved wear resistance and importantly does not negatively altering the electrophotographic properties of the organic photoconductor.
