Abstract: The present invention discloses a high weight percent of silicone within the silicone-urea block polymer for use with or as a dielectric layer material for electrostatic printing. The high weight percent comprises between about 66 and about 94 weight percent.

Abstract: An article comprising a substrate, and a textured, matte-finish, low adhesion backsize coating on one surface of the substrate, wherein the coating comprises polyvinyl carbamate having nitrogen-bonded hydrocarbon side chains which provide terminal alkyl groups more than five carbons in length.

Abstract: The invention provides electrographic imaging sheets comprising a substrate carrying a layer of dielectric material which has abhesive properties suitable for the release of a multicolored toner image from the dielectric surface during image transfer, while also having good toning properties during the several development stages of a multicolor toner imaging process.

Abstract: Diblock (B-A) and triblock (B-A-B) polydiorganosiloxane-polyurea block copolymers comprise non-functional polydiorganosiloxane endblock B and polyurea block A. When used to provide release coatings, the block copolymers allow for easier release compared to traditional block copolymers of the (AB).sub.n type having comparable amounts of polydiorganosiloxane. Articles incorporating the copolymers as a release material are also disclosed.

Abstract: A receptor sheet for thermal mass transfer imaging comprising a polymeric image-receptive layer comprising a polymer having a melt transition onset no higehr than the melting point of a compatible doner sheet wax, and having a melt viscosity at the melt temperature of said donor sheet wax of at least 1.times.10.sup.4 poise.

Abstract: Disclosed are image release sheets which comprise a dielectric coated substrate and a silicone-urea block polymer coating for the dielectric substrate. The silicone-urea block polymer functions as a release coating when the image sheet is used in electrographic processes. Excellent transfer of an image from a donor element, comprising the silicone-urea block polymer as a release coating, to a receptor substrate occurs. In a preferred embodiment, a pH sensitive indicator such as thymolphthalein can be added to the release coating in order to monitor the thickness of the coating.
