  • Patent number: 6368716
    Abstract: This invention is directed to an adhesive composition comprising: A. 80-98% by weight, based upon the total amount of adhesive dry solids, of at least one latex copolymer comprising: (1) 20-55% by weight, based upon the weight of the copolymer, of at least one brominated aromatic monomer, (2) 5-15% by weight, based upon the weight of the copolymer, of a monomer selected from the group consisting of glycidyl acrylate, glycidyl methacrylate, and mixtures thereof, and (3) 40-60% by weight, based upon the weight of the copolymer, of at least one non-brominated monofunctional(meth)acrylate monomer; (4) 0-10% by weight, based upon the weight of the copolymer, of a monomer selected from the group consisting of acrylonitrile, methacrylonitrile, and mixtures thereof; B. 0-10% by weight, based upon the total amount of adhesive dry solids, of at least one crosslinking agent; C. 1-10% by weight, based upon the total amount of adhesive dry solids, of at least one antimony oxide; and D.

  • Patent number: 4599299
    Abstract: A photohardenable element comprising a support bearing, in order, optionally a solvent-soluble nonphotosensitive layer, at least one photohardenable layer and a nonphotosensitive liquid removable layer, the photohardenable layer present immediately beneath the nonphotosensitive layer having therein substantially discrete, inert particles at least some of which cause protuberances in the nonphotosensitive layer. The particles have a size range of 0.1 to 10.0 .mu.m, not more than 50% by volume being below 3.5 .mu.m. A preferred element contains two photohardenable layers, the lower layer having an optical density greater than 3.0 over at least the 300 to 550 nm spectral region. The elements can be used for the preparation of proofs and printing plates.

  • Patent number: 4275140
    Abstract: Process for preparation of high opacity colored images on a photosensitive element surface which comprises bringing into surface-to-surface contact two elements, e.g., by laminating at elevated temperature, element (1) being a photosensitive element having tacky and nontacky image areas, and element (2) being an adhesively supported pigment/binder layer, 75 to 95 parts by weight pigment, e.g., TiO.sub.2, and 25 to 5 parts by weight elastomeric binder having a relatively low maximum tensile stress and a high elongation to break when cast as a film, and separating the two elements.
