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.
