  The invention relates to aqueous polymer dispersions suitable as reactive resin component (A) for a two-component reactive system. To obtain reactive systems which can be produced without solvents and which, in addition, combine good adhesion values with excellent optical properties of the laminates, good substrate wetting, high initial tack and high water resistance of the laminates, the dispersion is characterized in that at least 20% by weight of the polymer content emanates from an aqueous dispersion of OH-functional polyurethane prepolymers obtainable by reaction of a polyol component (I) containing polyester polyols and compounds containing at least two isocyanate-reactive groups and, in addition, groups capable of salt formation (II) with a stoichiometric excess of an isocyanate component (III) consisting of at least 20% by weight tetramethyl xylylene diisocyanate (TMXDI), subsequent dispersion in water and at least partial reaction of the remaining NCO groups with aminoalcohols (IV) and if desired, subsequent chain extension.
