  • Patent number: 6630283
    Abstract: A photosensitive element includes a layer of a photosensitive material on a transparent, multilayer, polymeric support having numerous alternating layers of at least two different polymeric materials. The polymeric multilayer support reflects at least 50% of actinic radiation in the range of wavelengths to which the photosensitive material is sensitive. If the polymeric multilayer reflector includes numerous, thin, alternating layers located at the surface of the polymeric support closest to the photosensitive material, the element not only provides increased speed but also provides an antihalation effect. In another aspect, a multilayer reflector is located a distance removed from the photosensitive layer sufficient to reduce any woodgrain that would otherwise occur, while increasing speed.

  • Patent number: 6479228
    Abstract: The present invention can relate to an imaging element including a support, an image-forming layer superposed on the support, and an outermost scratch resistant antistatic layer superposed on the support. The scratch resistant layer may include a polymer having a modulus greater than 100 MPa measured at 20° C., a filler particle with the proviso that the filler particle is not an electronically conductive crystalline metal oxide or a compound oxide thereof, and an electronically conducting polymer. The volume ratio of the polymer to the filler particle may be between 70:30 and 40:60 and the electronically conducting polymer can be present at a weight concentration based on a total dried weight of the scratch resistant layer of between 1 and 10 weight percent.
