Coating materials which can be cured thermally and by means of acting radiation, use and method for the production thereof

A coating material curable thermally and with actinic radiation, comprising

• (A) at least one binder containing isocyanate-reactive functional groups and
• (B) a crosslinking component comprising one or more constituents comprising at least one of
• (i) isocyanate groups comprising at least one of free isocyanate groups or blocked isocyanate groups,
• (ii) reactive functional groups containing at least one bond which can be activated with actinic radiation,
• (iii) flexibilizing segments which as part of three-dimensional networks lower their glass transition temperature Tg, and
• (iv) hardening segments which as part of three-dimensional networks raise their glass transition temperature Tg;
• and mixtures there,
• with the proviso that the crosslinking component (B) comprises at least two constituents which both comurise (i) and (ii).
