摘要：
The present invention relates to a process for preparing radiation-curing binders containing allophanate groups by reacting, at temperatures of ≦130° C., A) one or more compounds containing uretdione groups with B) one or more OH-functional compounds which contain groups which react, with polymerization, with ethylenically unsaturated compounds on exposure to actinic radiation (radiation-curing groups), C) optionally NCO-reactive compounds other than B), in the presence of D) a catalyst containing at least one zinc compound, to form allophanate groups by opening the uretdione ring. The present invention also relates to the binders obtained by the process of the invention and to coating compositions containing these binders.
