  • Low gain positive acting diazo oxide pre-press proofing system with polyvinyl ether and particulate slip agent in adhesive layer
    Patent number: 4889787
    Abstract: A positive-acting photosensitive proofing element is constructed with a thermal adhesive layer having a Tg between 45.degree. C. and 60.degree. C., said adhesive comprising a polymer or copolymer derived from an ethylenically unsaturated monomer and 0.5 to 40% by weight of a polyvinyl ether polymer as a flexibilizer.
    Type: Grant
    Filed: April 25, 1988
    Date of Patent: December 26, 1989
    Assignee: Minnesota Mining and Manufacturing Company
    Inventor: Arlene K. Musser
  • Presensitized color-proofing diazo resin sheet with acrylic thermal adhesive layer
    Patent number: 4656114
    Abstract: A light-sensitive color proofing sheet is described for producing an image on various substrates. A light-sensitive continuous color layer is releasably attached to a carrier. Overlying the color layer is a water-insoluble transparent colorless barrier layer. On the opposite surface of the barrier layer is a thermally laminable adhesive layer. Upon lamination of the sheet to a substrate, removal of the carrier and exposure to actinic radiation, the color layer is formed into an image, photomechanically, by removal of the non-image areas.

  • Narrow band light absorbing filter
    Patent number: 4601532
    Abstract: An optical transmission radiation filter absorbing between 320 and 500 nm comprises a polymeric film having a benzylidene or naphthalamide dye in combination with a phenol-formaldehyde resin which shifts the absorbing wavelength of the dyes.

  • Exposure latitude improvement in printing positive-acting color pre-press proofs
    Patent number: 4571373
    Abstract: The exposure latitude of positive-acting, color pre-press proofing photosensitive articles can be improved by positioning an optical filter between the separation half-tone positive and the photosensitive article.
