  • Polyesters comprising recurring photoconductive and photocrosslinkable units and elements thereof
    Patent number: 4609606
    Abstract: A polyester comprising at least 12 mole percent polymerized recurring units containing an arylamine photoconductive component and at least 15 mole percent polymerized recurring units containing a photopolymerizable component and wherein each of said components is responsive to a different wavelength of light. The polyesters are useful in radiation-sensitive elements, particularly lithographic elements.
    Type: Grant

    Assignee: Eastman Kodak Company
    Inventors: Michael Scozzafava, Michel F. Molaire
  • Photoconductive compositions and elements containing naphthalene bis-dicarboximide compounds
    Patent number: 4442193
    Abstract: Photoconductive compositions comprising photoconductors and 1,4,5,8-naphthalene bis-dicarboximide sensitizing compounds are disclosed. Compositions and elements containing such compounds are sensitized to radiation below 400 nm. Embodiments are disclosed in which the photoconductor is an arylalkane leuco base. Such embodiments are advantageously nonsensitive to radiation above 400 nm and are also nonpersistent.
