摘要： Multicomponent systems comprising(A) a component which contains isocyanate-reactive functional groups, is free from isocyanate groups, and contains reactive functional groups having bonds which can be activated with actinic radiation, or is free from these functional groups, and (B) a component which contains isocyanate groups, is free from isocyanate-reactive functional groups, and contains reactive functional groups having bonds which can be activated with actinic radiation, or is free from these functional groups, one of the two components, (A) or (B), containing functional groups having bonds which can be activated with actinic radiation, and component (A) comprising (L) a light stabilizer, selected from the group consisting of low molecular mass, oligomeric and polymeric light stabilizers which contain at least one isocyanate-reactive functional group and(P) a photoinitiator which contains at least one isocyanate-reactive functional group; processes for preparing them, and their use for preparing mixtures curable thermally and with actinic radiation.
