  • Negative-acting no-process printing plates
    Patent number: 6171735
    Abstract: A photosensitive composition is prepared containing a polymer of the formula B(X)(Y) wherein B represents an organic backbone, each X independently is an acidic group or salt thereof and each Y independently is a photocurable group and a photoinitiating compound or compounds. Preferably, free-radically polymerizable multi-functional monomer and/or oligomer is added to the photosensitive composition. The photosensitive composition can be coated on a suitable substrate for planographic printing plate applications. Imagewise irradiation causes the light struck regions to photocure, becoming insoluble in aqueous and organic mediums, while the non-light struck regions remain highly soluble/dispersable. Printing plates of this construction do not require processing prior to being run on a press.
    Type: Grant
    Filed: November 23, 1998
    Date of Patent: January 9, 2001
    Assignee: 3M Innovative Properties Company
    Inventors: Minyu Li, James P. Gardner, John E. Kluge, Sumita B. Mitra
