Abstract
This invention discloses novel surface release layers on temporary image receptors particularly suited to the requirements of liquid electrographic (both electrophotographic and electrostatic) printing on a variety of receptors. The inventive temporary image receptors are comprised of a surface release layer on a photoreceptive or dielectric substrate. The release layers are silicone copolymers which are chemically modified to improve imaging, drying or transfer performance when used in the simplified color electrophotography (SCE) or electrostatic printing processes.
