REACTION PRODUCT OF OLEFINICALLY UNSATURATED COMPOUNDS WITH COMPOUNDS CONTAINING ACTIVE HYDROGEN, PROCESSES FOR THEIR PREPARATION AND 2-COMPONENT LACQUERS BASED THEREON

摘要

of the disclosure: Reaction products of A) compounds containing at least two R1R2C=CR3-X groups (I) with B) compounds which contain: a) at least two active H atoms or b) at least two groups having active H atoms of the type -AH- (II) or c) at least one active H atom and at least one group of the type (II), or which form the corresponding amount of this group (II), in which, in formula (I), X denotes -CO- which is attached to a further R1R2C= CR3-X group either directly or via the radical of a polyhydric alcohol or of an amine, R1 denotes hydrogen or a hydrocarbon radical having 1 to 10 carbon atoms, R2 denotes hydrogen, a hydrocarbon radical having 1 to 10 carbon atoms, an ester group containing the radical R4 of a monohydric alcohol having up to 12 carbon atoms, -CN, -NO2 or a CO-NHR1 or CO-R1 group, R3 has the same meaning as R2, and in formula (II), -AH- denotes one of the groupings -CH-, -NH- and -SH. These compounds are prepared with the use of specific catalysts and can be employed in the form of 2-component systems as binders for coatings which cure rapidly at room temperature and at elevated temperatures.
