Abstract
A display and printing method using an electrochromic imaging material. The electrochromic material forms a colored image in response to the formation of an image pattern on a photoconductive surface. The electrochromic material is between an electrode and the photoconductive surface when image formation takes place. The image may be utilized in a display device or in printing.
Claims6
A printing method comprising forming a layer of electrochromic material on a conductive electrode, bringing an image recording element into contact with said electrochromic material said image recording member comprising a photoconductive layer contacting the electrochromic material, applying electromagnetic radiation in an image pattern to said photoconductive layer, applying a bias voltage to the conductive electrode to form a colored ink attractive image of said electrochromic material on said conductive electrode, applying ink to said image and transferring the ink image to an image receiving surface.
