ABSTRACT:
A photoreceptor with good mechanical and physical properties is provided with an overcoat layer comprising a copolymer of an α,β-ethylenically unsaturated carboxylic acid and an α,β-ethylenically unsaturated monomer wherein the weight percent of the α,β-ethylenically unsaturated carboxylic-acid is at least 25% up to 99% of the copolymer. The copolymer may comprise an α,β-ethylenically unsaturated carboxylic acid and an α,β-ethylenically unsaturated monomer wherein the copolymer has an acid value of at least 150 mg KOH/g the copolymer. The copolymer may be present in a blend with a second polymer or copolymer comprised of units derived from a second α,β-ethylenically unsaturated monomer that is different from the an α,β-ethylenically unsaturated carboxylic acid and/or the α,β-ethylenically unsaturated monomer. The copolymer or the copolymer blend may be present in a layer that is crosslinked or crosslinkable, the crosslinking being effected through a distinct crosslinking agent that reacts with group(s) on the an α,β-ethylenically unsaturated carboxylic acid or the α,β-ethylenically unsaturated monomer.
