  • Positive-working radiation-sensitive imageable elements
    Patent number: 8298750
    Abstract: Positive-working imageable elements having improved sensitivity, high resolution, and solvent resistance are prepared using a water-insoluble polymeric binder comprising vinyl acetal recurring units that have pendant hydroxyaryl groups, and recurring units comprising carboxylic acid aryl ester groups that are substituted with a cyclic imide group. These imageable elements can be imaged and developed to provide various types of elements including lithographic printing plates.
    Type: Grant
    Filed: September 8, 2009
    Date of Patent: October 30, 2012
    Assignee: Eastman Kodak Company
    Inventors: Moshe Levanon, Georgy Bylina, Vladimir Kampel, Marina Rubin, Larisa Postel, Tanya Kurtser, Moshe Nakash
  • Radiation-sensitive compositions and elements containing poly(vinyl hydroxyaryl carboxylic acid ester)s
    Patent number: 8048609
    Abstract: A radiation-sensitive composition can be used to prepare positive-working imageable elements having improved sensitivity and solvent resistance. These elements are useful for making lithographic printing plates and printed circuit boards. The composition includes a water-insoluble polymeric binder that has at least 20 mol % of recurring units comprising hydroxyaryl carboxylic acid ester groups, some of which can be substituted with cyclic imide moieties.
    Type: Grant
    Filed: December 19, 2008
    Date of Patent: November 1, 2011
    Assignee: Eastman Kodak Company
    Inventors: Moshe Levanon, Georgy Bylina, Vladimir Kampel, Larisa Postel, Marina Rubin, Tanya Kurtser
  • Radiation-sensitive compositions and elements with solvent resistant poly(vinyl acetal)s
    Patent number: 7955779
    Abstract: A radiation-sensitive composition can be used to prepare positive-working imageable elements having improved solvent resistance and is useful for making lithographic printing plates. The composition includes an alkaline soluble polymeric binder that is a specific poly(vinyl acetal) that exhibits improved resistance to press chemicals, and a radiation absorbing compound.
