A coating composition, comprising:
- a urethane (meth)acrylate (A) comprising, as formation components:
- (a) at least one isocyanate having at least 2 isocyanate functions,
- (b) at least one polyalkylene oxide polyether having at least 2 hydroxyl functions,
- (c) at least one hydroxy-functional (meth)acrylate having exactly one hydroxyl function and at least one (meth)acrylate function,
- (d) at least one compound having at least one isocyanate-reactive group and at least one acid function,
- (e) optionally at least one compound having at least one isocyanate-reactive group and at least one basic group for neutralization of the acid groups of component (d),
- (f1) at least one monofunctional polyalkylene oxide polyether alcohol having a number-average molecular weight Mn of at least 600 g/mol,
- (f2) optionally at least one monoalcohol (f2) having exactly one hydroxyl function and no further functional group beyond that,
- (g) optionally at least one di- or polyamine, and
- (h) optionally at least one primary or secondary amine (h) for activation of the (meth)acrylate group.
