Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a polyurethane aqueous dispersion which is curable with high-energy radiation particularly UV radiation, contains an organic solvent by an amount as small as possible, exhibits physical drying properties at room temperature, and strongly adheres onto a wood substrate exhibiting excellent warm-feeling and gloss of wood, and forming a film high in hardness. SOLUTION: The new UV-curable polyurethane dispersion is on the basis of an unsaturated polyester modified with dicyclopentadiene. The production of the dispersion and uses thereof as a lacquer, a coating and/or an adhesive, are also disclosed. COPYRIGHT: (C)2008,JPO&INPIT
