    摘要: The present invention relates to radiation curable aqueous polyurethane dispersions containing 0.05 to 20 wt. %, based on the weight of the non-aqueous constituents of the aqueous polyurethane dispersions, of 2,2-dimethyl-3-hydroxypropionic acid-(2,2-dimethyl-3-hydroxypropyl ester), (HPSNPG, calculated as MW 204.3). The invention also relates to substrates coated with these polyurethane dispersions, in particular to coated wood substrates with good grain enhancing properties.
