Abstract
A repellent composition containing an oil of low volatility having a surface energy less than 27 dynes/cm. and a solid fluorinated polymer such as a polymer of a fluoroalkyl acrylate. In accord with certain embodiments of the invention, a resinous binder and/or a particulate fluorocarbon powder may be added to the repellent composition. The repellent composition may be used to prepare an ink repellent surface for a "waterless" lithoplate or as a coating on the surface of an electrographic element from which a liquid developed electrographic image is transferred.
