  • Publication number: 20020160285
    Abstract: A photosensitive media cartridge includes an ambient condition sensor mounted in the cartridge for sensing ambient conditions in the cartridge. When the cartridge is positioned at a media transfer position on an image-forming device that permits the conveyance of media from the cartridge to the image-forming device, image development or printing on the media in the image-forming device is controlled based on the sensed ambient conditions in the cartridge. The ambient condition sensor includes a cover layer and a conductive layer, wherein a rate of response to ambient conditions of the cover layer matches rate of response to ambient conditions of the photosensitive media to be developed. As a further option, the media itself can include a conductive layer so that the media can be the sensor.

  • Publication number: 20010019760
    Abstract: Provided is a direct imaging lithographic printing plate by having on a support a hydrophilic image-receiving layer comprising a polymer compound that is chemically bonded directly to the support surface and has hydrophilic functional groups. Therein, the hydrophilic functional groups preferably have capabilities of forming chelates together with polyvalent metal ions. The polymer compound may be chemically bonded directly to the support surface at its molecular chain end or may be chemically bonded to a polymer backbone chemically bonded to the support surface at its molecular chain end.

  • Publication number: 20010005572
    Abstract: The present invention is an imaging element which includes a support, an imaging layer superposed on a side of said support and an overcoat overlying the imaging layer. The overcoat is composed of an organic polymer. The overcoat is discontinuous such that a fraction of the surface area of the imaging layer remains uncovered by said polymer, wherein the fraction of area not covered by the said polymer is from 0.02 to 0.98. The present invention is a photographic which includes a support, a silver halide emulsion layer superposed on a side of said support and an overcoat overlying the silver halide layer. The overcoat is composed of an organic polymer. The overcoat is discontinuous such that a fraction of the surface area of the silver halide emulsion layer remains uncovered by said polymer, wherein the fraction of area not covered by the said polymer is from 0.02 to 0.98. In one embodiment, the discontinuous overcoat is a series of parallel stripes.
