| 摘要 |
The invention relates to multi-component systems, containing (A) a component which contains isocyanate reactive functional groups, is devoid of isocyanate groups and contains reactive functional groups comprising compounds which can be activated by means of actinic radiation, or is devoid of said functional groups, and (B) a component which contains the isocyanate groups, is devoid of isocyanate reactive functional groups and contains reactive functional groups comprising compounds which can be activated by means of actinic radiation and is devoid of said functional groups. One of the two components (A) or (B) contain functional groups provided with compounds which can be activated by actinic radiation, and the component (A) contains (L), a light-protection agent, selected from the group comprising low molecular light protection agents, oligomers and polymers which contain at least one isocyanate reactive functional group, and (P) a photo initiator which contains at least one isocyanate reactive functional group. The invention also relates to a method for the production thereof and to the use thereof for producing thermal mixtures which can be hardened by means of actinic radiation.
