The present invention relates to aqueous polyurethane dispersions that comprise selected nonionic dispersing agents selected from the group consisting of ethoxylated triglyceride; alkylpoly-ethylene glycol ether of a linear, saturated C16-C18 fatty alcohol; and a linear, saturated C12-C14alcohol etherified with a poly-C2-C3alkoxy ether. The dispersions are UV-radiation curable and are useful for the preparation of grain enhanced coating compositions.
本发明涉及一种
