Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a radiation-curable urethane- functional prepolymer PU, by reacting an isocyanate-functional component A with an OH-containing component B. SOLUTION: A component A comprises at least one trifunctional isocyanate compound A1 and optionally one or more bifunctional isocyanate compound A2. An OH-containing component B is composed of at least one OH-containing compound B1 containing at least one reactive OH group and optionally a different OH-containing compound B2. In the production, the component A consists of the two different isocyanate compounds A1 or one isocyanate compound A1 and at least one isocyanate compound A1 or the component B is composed of at least the two different compounds B1.
