Photoconductors are disclosed having an overcoat layer of silsesquioxane substituted with 4-[3-(triethoxysilylpropoxy]-2-hydroxybenzophenone. The degree of substitution is believed not critical. Similarly, the thickness of the coating is not critical and may vary according to the wear anticipated, as well as the electrical requirements of the specific application. Improvements are realized using this material in comparison to unsubstituted silsesquioxane.
