Abstract: The invention relates to aqueous polymer dispersions for composite film lamination, said dispersions containing a dispersed polymer and a dissolved polymer, and to a multiple-step method for the production of same from ethylenically-unsaturated, radically polymerizable monomers. In a first step, a first polymer is produced through radical emulsion polymerization. In a second step, an aqueous polymer dispersion is produced in the presence of the first polymer. The monomers of the first step comprise monomers having acid functional groups. The dissolved polymer comprises monomers having oxazoline groups and water-soluble monomers. The aqueous polymer dispersions can be used as an adhesive for the production of composite films.
