Abstract
A novel process is disclosed for the manufacture of protected, distortion-free, full-color electrographic images for use on large format posters, billboards and the like. A novel electrographic element is also disclosed, which includes a base, a release layer and a combined transparent dielectric and adhesive layer which is substantially tack-free, at ambient pressure and temperature. The novel electrographic imaging process includes the steps of: A) producing a toned image layer on the surface of the electrographic element and B) pressure laminating the receptor substrate, optionally at an elevated temperature to the toned image layer to form the completed electrographic image. The base and release layer may be stripped from the dielectric/adhesive layer which then serves to protect the transferred, toned, electrographically generated image from abrasion and environmental contaminants.
