  • Imaging element having a conductive polymer layer
    Patent number: 6171422
    Abstract: An electrographic imaging element useful for forming colored images is described. The element contains an imaging layer structure and a support structure. The support structure contains an electrically conductive polymeric release layer formed by polymerizing a mixture containing a polymerizable, ethylenically unsaturated ammonium precursor; a polymerizable, ethylenically unsaturated, organo-silicone precursor; a polymerizable precursor containing at least two polymerizable, ethylenically unsaturated functional groups; optionally, a polymerizable, ethylenically unsaturated acidic precursor containing at least one carboxylic acid group; and, optionally, a monofunctional precursor containing one polymerizable, ethylenically unsaturated functional group. The element is particularly useful for forming large size images, such as are required for banners, billboards, and other out-of-doors advertisements.
    Type: Grant
    Filed: June 26, 1998
    Date of Patent: January 9, 2001
    Assignee: Rexam Graphics, Inc.
    Inventors: Douglas Allan Cahill, Everett Wyman Bennett, Weitong Shi, Edward William Sporbert, Alan Richard Taylor, Dene Harvey Taylor
