Abstract: Described are aqueous adhesive dispersions comprising dispersed polyurethanes and also ethoxylated fatty alcohols as emulsifiers. The polyurethanes are constructed from certain organic diisocyanates, dihydroxy compounds selected from certain polyester diols and polyether diols, and compounds having groups reactive toward isocyanate groups and having at least one ionic group. The adhesive dispersions can be used as laminating adhesives, for example for composite film lamination or for the lamination of rigid moldings with flexible decorative foils.

Abstract: A method is described for debonding a bonded article. The bonded article comprises at least two components which are bonded to one another by means of a polyurethane adhesive selected from aqueous polyurethane dispersion adhesives and polyurethane hotmelt adhesives. At least one of the components is a thermoplastic polyurethane. The components are debonded by treatment with an aqueous surfactant composition at elevated temperatures.
