ABSTRACT:
A composition forms an overcoat layer for an organic photoreceptor by combining an organic silane compound, an acrylic polymer, polyvinyl butyral and a solvent. The organic photoreceptor has increased electrical and mechanical properties, leading to improved life characteristics. Also, unlike when a single material of either acrylic polymer or silsesquioxane is used in forming an overcoat layer, when the composition of the present invention is used, it is not necessary to coat a primer or an adhesive layer, thereby simplifying a coating process and reducing the cost required in forming additive layers.
