Abstract: The invention relates to an aqueous two-component adhesive and use thereof, in particular to the use for laminating a rigid substrate and a plastic film, a laminated product comprising the adhesive, and a method for producing a laminated product. The aqueous two-component adhesive comprises component A and component B, the component A comprising more than 50% by weight and not more than 99% by weight of an aqueous polyurethane dispersion; the B component comprising 1% by weight to 16% by weight of water-dispersible modified polyisocyanate based on hexamethylene diisocyanate, the above weight percentage based on the amount of the adhesive being 100% by weight; wherein the aqueous polyurethane dispersion comprises polyurethane dispersed therein, the enthalpy of melting of the polyurethane being 26 to 100 J/g, preferably 30 to 100 J/g, particularly preferably 30 to 60 J/g, measured at 20° C. to 100° C. for the first heating curve by DSC according to DIN65467 (1999).
