  • Patent number: 5176974
    Abstract: Disclosed are ionographic imaging apparatuses and processes. One apparatus comprises an imaging means, means for applying to the imaging means a liquid material capable of forming a dielectric peel layer adhering to the imaging means, ionographic writing means for generating a latent image on the peel layer, means for developing the latent image on the peel layer, and means for simultaneously transferring the peel layer bearing the developed image from the imaging means to a substrate and affixing the peel layer bearing the developed image to the substrate.

  • Patent number: 5021318
    Abstract: Disclosed is a process for forming secure images which comprises electrostatically charging an imaging member; imagewise exposing the charged member, thereby forming a latent image on the member; developing the latent image with a liquid developer comprising a liquid medium, a charge control additive, and toner particles comprising a colorant and a polymeric material; allowing the developed image to dry on the imaging member; contacting the portion of the imaging member with the dry developed image with a substantially transparent sheet having an adhesive material on the surface thereof in contact with the imaging member, thereby transferring the developed image from the imaging member to the substantially transparent sheet; contacting the adhesive surface of the substantially transparent sheet with the developed image with a paper sheet having a polymeric coating on the surface that is in contact with the substantially transparent sheet; and applying heat and pressure to the substantially transparent sheet a

  • Patent number: 4485260
    Abstract: There is disclosed a process for the production of unsymmetrical, substituted diarylamines by the reaction of a primary aromatic amine and a substituted phenol wherein the phenol is held in excess of the primary aromatic amine thereby minimizing by-product formation as a result of self-condensation of the primary arylamine. The desired secondary amine is produced in high yield and purity by recycling the unreacted phenol.

    Inventors: Paul Szabo, Daniel E. Freeman, Trevor I. Martin, John M. Lennon
  • Patent number: 4299983
    Abstract: A process for the production of symmetrical and unsymmetrical substituted diarylamines is disclosed. The process provides said diarylamines in high yield and purity by the reaction of a salt of an arylsulfonic acid and an alkali metal salt of a primary arylamine in the presence of an inorganic alkali metal salt.
