Abstract
The present invention relates to a hydrophobic overcoat for an electrophotographic element. The overcoat contains a polymeric composition such as a homopolymer, copolymer, or blend thereof and an .alpha.,.beta.-ethylenically unsaturated carboxylic acid or the partial alkyl ester thereof and a relatively large amount of cross-linking agent for said polymeric composition, for example, an imine-terminated cross-linking agent or a melamine-formaldehyde resin.
