Abstract
Aqueous coating compositions based on polyurethane dispersions which cure under the influence of high-energy radiation, to a process for preparing them and to their use. The coating compositions contain a polyisocyanate, a polyurethane containing free-radically polymerizable groups, and an initiator which is capable of initiating a free-radical polymerization.
Claims18
Aqueous coating compositions comprising
- (I) at least one polyisocyanate,
- (II) at least one polyurethane which contains free-radically polymerizable groups and up to 0.53 mmol/g, of groups containing Zerevitinov-active hydrogen atoms, and
- (III) an initiator which is capable of initiating a free-radical polymerization.
