Output (English): In the present invention there is disclosed the use of water dispersion containing polymers from which at least 20 percent by weight are formed by water dispersion of polyurethane prepolymers having OH functional groups and obtainable by reaction of a polyol component (I) containing polyester polyols and compounds (II) containing groups capable of forming salts and at least two bonds with isocyanates, with an isocyanate component (III) consisting of at least 20 percent by weight of tetramethyl xylylene diisocyanate in stoichiometric excess, further by subsequent dispersion in water and at least partial reaction of the remaining NCO groups with aminoalcohols (IV) a eventually by subsequent elongation of the chain as polyurethane primer, for adhesive bonding plastic materials and backing plastic materials, particularly PVC with PVC, PES sheets, polyolefins and polymethyl methacrylates. As adhesive, the reactive polyurethane fusion adhesive is preferably used. By using primers, both high
