ABSTRACT:
A novel two step 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, which is used in the process, comprises a carrier layer; optionally, a protective layer; a conductive layer; a dielectric layer; and a substantially tack-free, adhesive layer which is activated at a pressure and a temperature which is above ambient pressure and temperature of the electrographic element. The novel electrographic imaging process comprises: A) producing a toned image layer on the surface of the electrographic element, so that the toned image layer is adhered to the surface of the adhesive layer; and B) pressure laminating the receptor substrate at an elevated temperature to the toned image layer to form the completed electrographic image. Optionally, the carrier layer is stripped from the conductive or protective layer which then serves to protect the electrographic image from abrasion and environmental contaminants. Alternatively, the carrier layer is conductive and, along with the conductive layer (if present), is stripped from the dielectric layer which then serves to protect the electrographic image from abrasion and environmental contaminants.
