Abstract:
A water-based polyurethane dispersion including a chain-extended polyurethane, characterized in that the polyurethane dispersion includes 2,5,7,10-tetraoxaundecane. The water-based polyurethane dispersion is suitable as a non-hazardous water-based coating composition for coatings with a particularly good adhesion on plastic or rubber substrates. The solvent 2,5,7,10-tetraoxaundecane contained therein imparts good film coalescing, good adhesive properties and high strength of the polyurethane dispersion.

Claim (Index 6):
The water-based polyurethane dispersion according to  claim 5 , wherein the isocyanate-terminated polyurethane prepolymer is a reaction product of\n at least one first polyol, at least one second polyol, which is different from the first polyol, and at least one diisocyanate, wherein the at least one second polyol is selected from a polyether polyol having ethylene oxide units, a polyol having an acid group and a polyol having an amine group.
