    • A polymer dispersion comprising an aqueous, continuous phase and dispersed particles of polyurethane, which is based on organic, non-aromatic isocyanates with a functionality of at least 2, said polyurethane having a high degree of crystallinity and whose crystalline phase has a melting point between 25 and 70° C., and a copolymer and/or terpolymer having a Tg (glass transition temperature) between −20 and +50° C. obtainable by emulsion polymerization of ethylenically unsaturated monomeric materials containing only C, H, O and/or N atoms, which monomeric materials comprise from 0.5 to 15 percent on the total of monomeric materials of monomers containing at least one nitrile group, in a weight ratio between 50:50 and 10:90 (polyurethane to emulsion polymer), in which the particles of the dispersion are in the form of multiphase particles comprising said polyurethane and said copolymer and/or terpolymer and which dispersion is obtainable by emulsion polymerization of the monomeric materials in the presence of the polyurethane dispersion, said eventual polymer dispersion having a solids content of 30 to 70%. The invention also comprises the use of these dispersions as an adhesive, especially for heat seal laminating, preferably for 3-D(imensional) Laminating. The dispersion is also useful as a size for glass fibers.

    • A description is given of aqueous polyvinyl ester dispersions comprising a) at least one vinyl ester copolymer derived from at least one vinyl ester of a monocarboxylic acid, at least one ethylenically unsaturated monomer containing N-alkylol groups and/or derivatives of N-alkylol groups, and, if desired, further comonomers, b) at least one protective colloid, c) at least one carboxylic acid and/or salt thereof, containing at least one further radical selected from the group consisting of hydroxyl, amino, carboxyl, carboxylic ester, and carboxylic amide radicals, and d) at least one water-soluble salt of a divalent metal ion. These dispersions are especially suitable for adhesively bonding porous or semiporous substrates, such as wood. Adhesive bonds of high strength and water resistance can be produced that do not exhibit discoloration. The dispersions can be used more particularly as veneer adhesives.
