    • Process for preparing binders including reacting A) one or more NCO-functional compounds containing uretdione groups with B) one or more compounds containing groups capable of participating in polymerization reaction with ethylenically unsaturated compounds on exposure to actinic radiation, and contain isocyanate-reactive groups, followed by C) reaction with one or more hydroxyl-containing compounds other than B), wherein at least one of these compounds has an OH functionality of ≧2, D) in the presence of one or more compounds containing phenoxide groups, as catalysts, and E) optionally auxiliaries and additives, where the reaction with compounds of component C) proceeds at least proportionally with the formation of allophanate groups and where and including binders containing allophanate groups and groups capable of participating in a polymerization reaction with ethylenically unsaturated compounds on exposure to actinic radiation, and optionally also contain NCO-reactive groups. The binders are used in coating compositions used to coat substrates.
    • 制备粘合剂的方法包括使A)一种或多种含有脲二酮基团的NCO-官能化合物与B)一种或多种含有能够在曝光于光化辐射下参与与烯属不饱和化合物聚合反应的基团的化合物,并含有异氰酸酯反应性基团, 随后C)与除B)之外的一种或多种含羟基化合物反应,其中这些化合物中的至少一种具有> = 2的OH官能度,D)在一种或多种含有酚盐的化合物的存在下,作为催化剂 和E)任选的助剂和添加剂,其中与组分C)的化合物的反应至少与形成脲基甲酸酯基团成比例地进行,并且其中和包括含有脲基甲酸酯基团和能够与烯属不饱和化合物进行聚合反应的基团的粘合剂 暴露于光化辐射,并且任选地还含有NCO-反应性基团。 粘合剂用于涂覆基材的涂料组合物中。
