A process for preparing binders containing allophanate groups which contain, at the oxygen atom of the allophanate group that is bonded via two single bonds, organic radicals with activated groups capable of participating in a polymerization reaction with ethylenically unsaturated compounds on exposure to actinic radiation; the process includes reacting A) one or more compounds containing uretdione groups with B) one or more OH-functional compounds which contain groups capable of participating in a polymerization reaction with ethylenically unsaturated compounds on exposure to actinic radiation, and C) optionally further NCO-reactive compounds, and D) in the presence of one or more compounds containing phenoxide groups, as catalysts. The binders can be used in preparing coatings, coating materials, coating compositions, adhesives, printing inks, casting resins, dental compounds, sizes, photoresists, stereolithography systems, resins for composite materials and sealants.
一种制备含有异氰酸酯基团的粘合剂的方法,其中在通过两个单键连接的异氰酸酯基团的氧原子上含有具有活性基团的有机基团,能够在暴露于光辐射下参与与乙烯基不饱和化合物的聚合反应; 该方法包括反应A)含有脲二酮基团的一个或多个化合物与B)一个或多个含有能够在暴露于光辐射下参与与乙烯基不饱和化合物的聚合反应的基团的OH-官能化合物,以及C)可选的进一步NCO反应性化合物,和D)在含有酚氧基团的一个或多个化合物的存在下,作为催化剂。这些粘合剂可用于制备涂层、涂料、涂层组合物、粘合剂、印刷油墨、铸造树脂、牙科化合物、尺寸、光阻剂、立体光刻系统、复合材料树脂和密封剂。
