  • Patent number: 8623166
    Abstract: A method of forming on a substrate an adhesive region that includes an adhesive composition employs steps of: a) applying a dispersion of the adhesive composition in a solvent to an anilox roller on a flexographic press, said adhesive composition comprising an adhesive polymer; b) contacting the anilox roller with a flexographic plate to transfer a portion of the dispersion thereto, said flexographic plate comprising an adhesive application region having a shape substantially matching that of the adhesive region on the substrate; c) contacting the flexographic plate with the substrate to transfer the dispersion to the substrate; and d) drying the dispersion on the substrate to form the adhesive region.

  • Patent number: 5571857
    Abstract: A method for preparing an aqueous adhesive polyurethane/acrylic polymer dispersion by reacting a polyol, a carboxylic acid-containing polyol and a polyisocyanate to form an anionic, water dispersible prepolymer, subsequently chain extending to form the polyurethane component of the polyurethane/acrylic polymer and polymerizing at least one acrylic monomer in the presence of the prepolymer and/or polyurethane to form the acrylic polymer component, characterized by using isophorone diisocyanate as the polyisocyanate and performing the chain extension with a composition comprising a monofunctional amine and a difunctional amine in a 1:4 to 4:1 weight ratio.
