  • Radiation-sensitive composition containing a resole resin, a novolac resin, a latent bronsted acid, an infrared absorber and terephthalaldehyde and use thereof in lithographic printing plates
    Patent number: 5466557
    Abstract: A radiation-sensitive composition especially adapted to prepare a lithographic printing plate that is sensitive to both ultraviolet and infrared radiation and capable of functioning in either a positive-working or negative-working manner is comprised of (1) a resole resin, (2) a novolac resin, (3) a latent Bronsted acid, (4) an infrared absorber, and (5) terephthalaldehyde. The solubility of the composition in aqueous alkaline developing solution is both reduced in exposed areas and increased in unexposed areas by the steps of imagewise exposure to activating radiation and heating.
    Type: Grant
    Filed: August 29, 1994
    Date of Patent: November 14, 1995
    Assignee: Eastman Kodak Company
    Inventors: Neil F. Haley, Steven L. Corbiere
