Radiation-curable, aqueous dispersions, production and use thereof

Abstract

The present invention relates to polyester acrylate/urethane dispersions based on polyester acrylate prepolymers containing hydroxyl groups, obtainable by polyaddition of A. 40-90 wt. % of one or more polyester acrylate prepolymers containing hydroxyl groups and having an OH content of 40-120 mg of KOH/g and B. 0.1-20 wt. % of one or more mono- and/or difunctional compounds reactive towards isocyanate groups, which compounds contain groups which are cationic, artionic and/or have a dispersant action due to ether groups with C. 10-50 wt. % of one or more polyisocyanates D. 0.0-30 wt. % of polyols together with a subsequent reaction with E. 0.1-10 wt. % of one or more di- and/or polyamines.
