Abstract
A novel process for forming protected, electrographic image on a substrate is disclosed. An electrographic element used in the process comprises a supporting layer, a conductive layer, and a dielectric layer. A protective element used in the process comprises a temporary support layer, a protective layer, and an adhesive layer. The novel electrographic imaging process comprises the steps of producing a toned electrographic image on the surface of the electrographic element; applying and adhering the adhesive layer of the protective element to the toned electrographic image to form an imaged composite; removing the supporting layer from the composite to uncover the conductive layer; pressure laminating the final substrate to the conductive layer; and then removing the temporary support layer from the protective layer to form the protected, electrographic image on the substrate of choice. The process is useful in manufacturing protected images of all sizes and is particularly suited to making large format images such as billboards.
