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.
