  • Publication number: 20040063809
    Abstract: An inkjet ink binder including polymeric nanoparticles (“PNPs”) having a mean diameter in the range of 1 to 50 nanometers, wherein the PNPs include as polymerized units 1-20%, by weight based on dry polymer weight, of a curable composition. The reaction of the curable composition can be initiated thermally, chemically or via actinic radiation. An inkjet ink composition comprising a liquid medium, a colorant and the inkjet binder and a method for improving the durability of inkjet ink printed on a substrate are also provided.

  • Patent number: 6203916
    Abstract: An aqueous adhesive composition for wet lamination of substrate layers to form a laminated article includes from about 40 weight percent to about 65 weight percent solids dispersed in an aqueous medium, wherein the solids include a polymer having repeating units derived from a vinyl ester monomer and having a glass transition temperature of about −15° C. to about +15° C.; and from about 0.1 parts by weight to about 40 parts by weight of a plasticizer compound per 100 parts by weight of the polymer. A method for making a laminated article includes applying a wet layer of the aqueous laminating adhesive composition of the to a first substrate layer; covering the wet layer of adhesive composition with a second substrate layer; and drying the layer of adhesive composition to form the laminated article. A laminated article includes two substrate layers bonded together by an interposed layer of the dried adhesive composition.
