  • Visible image dyes for positive-acting no-process printing plates
    Patent number: 5665522
    Abstract: Positive-acting no-process printing plates are disclosed in which a stable visual or print-out image is obtained upon exposure of the plate to actinic radiation. The visual image is obtained by incorporation into the photosensitive layer, a dye which is irreversibly bleached upon exposure of the printing plate. For example, an acid which is generated upon exposure of a photopolymer to radiation may be used to bleach a dye of this invention. The visual or print-out images produced are useful in the production cycle and are stable to basic environments that may be encountered in the production setting.
    Type: Grant

  • Antistatic films
    Patent number: 4532185
    Abstract: A hydroxyorganosilane composition which upon curing provides a polymer that is an electrical conductor is disclosed. The composition comprises 1 to 95 weight percent of a hydrolyzate of a hydroxyorganosilane and optionally up to 50 weight percent of a silanol-sulfonate compound. When the cured polymer, which has a siloxane backbone, is a film in a composite structure, the resultant article has antistatic properties.
