The element contains, in order: (a) a backside conductive layer; (b) a base; (c) a frontside conductive layer; and (d) a dielectric layer. The element has a wet shrinkage of less than about 2% in the machine direction and less than about 2%, preferably less than about 1%, in the cross-machine direction. In one embodiment the frontside conductive layer is a radiation cured conductive layer. In another embodiment the backside conductive layer is adhesive. In another embodiment the element additionally comprises a filled layer between the base and the frontside conductive layer.

Abstract: A process and associated element for forming an image on an substrate using an electrographic element comprising a releasable dielectric image receptive layer supported on an electrically conductive carrier sheet by applying an adhesive coating on the substrate front surface, producing a toned image on the image receptive dielectric layer, contacting the image to the adhesive layer thereby adhering the electrographic element to the substrate, and separating and removing the carrier sheet from the image receptive layer, whereby the image receptive layer and the toned image remain on the substrate.

Abstract: Novel electrographically produced products are disclosed which include large format posters, billboards and the like produced by a process employing a novel electrographic element 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 new product is made by an imaging process involving:A) producing a toned image layer on the surface of the electrographic element and B) pressure laminating a receptor substrate 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.

Abstract: Provided is an electrographic printing paper suitable for the printing of a quality image, which printing paper is pastable and is therefore useful in pastable displays, including outdoor billboards. The electrographic printing paper is comprised of a dielectric coating on a conductive base paper which exhibits wet strength and wet expansion properties suitable for pasted displays. The conductive base paper contains a wet strength agent and a sizing or coating of a conductivizing composition comprised of a binder and a substantially water insoluble conductivizing agent.

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.
