  • Patent number: 10597549
    Abstract: The present invention provides a blend of a soft water reducible polyurethane with a high percentage of tethered ethylene oxide rich chains and a harder acrylic copolymer with specified percentages of repeat units from C1-C12 esters of acrylic and/or methacrylic acid and an acid component from combined acrylic and methacrylic acid. The blend forms the binder in a coating that exhibits the possibilities of having high gloss, transparency, and facilitating the conversion of inks applied to the coating to a smudge resistant image in a short period of time after application of the ink.

  • Patent number: 8383713
    Abstract: The water-resistance properties of polyester-based polyurethanes are remarkably enhanced, without adversely affecting the transparency properties of these materials to any significant degree, by including in the polymer a substantially dispersed nano-particle proton scavenger. The hydrolytic stability and water-resistance properties of polyester-based polyurethanes are remarkably enhanced and match those of polycarbonate-based polyurethanes, without adversely affecting the transparency of these materials to any significant degree, by including in the polymer a substantially dispersed nano-particle proton scavenger such as calcium carbonate.

  • Patent number: 8242205
    Abstract: A novel method of preparing an aqueous dispersion of non-uniform polyurethane particles which comprises (a) preparing at least two isocyanate-terminated polyurethane prepolymers having different hydrophilicities; (b) preparing a uniform mixture of said prepolymers, and (c) dispersing the mixed prepolymers in an aqueous medium. The resulting dispersion of the prepolymers may optionally be chain extended. This method enables the preparation of core-shell particles as well as particles of other morphologies, including “raspberry”, interpenetrating network, “salt-and-pepper”, “ice-cream cone” and particles of gradient composition. Similarly, an aqueous dispersion of two different polyurethane polymers may be obtained by first preparing at least two different isocyanate-terminated polyurethane prepolymers, preparing a uniform mixture of such prepolymers and thereafter dispersing the mixture in an aqueous medium.

  • Patent number: 7943714
    Abstract: A water activated adhesive system is described that is particularly suited for applying non-paper polymeric labels to surfaces which have low moisture permeability. The adhesive system is characterized by a dry non-tacky surface that becomes tacky in less than one second when contacted with a water-based activator. While it is a water activated adhesive, it is also characterized after aging bonded to a substrate by resistance to adhesive failure during 72 hours of immersion in ice/water mixture. The adhesive is beneficial to allow use of existing paper labeling equipment with polymeric labels.

  • Publication number: 20100267299
    Abstract: Vinyl chloride polymer compositions, optionally plasticized, containing a hydrophilic polymer (e.g., a hydrophilic polyurethane or hydrophilic vinyl polymer) are described for use as coatings and films with increased moisture vapor transmission and/or static dissipative properties. Films from this material are useful as fluid barriers that allow diffusion of moisture vapors. Similar modifications can be made to acrylate and urethane polymers.
