Abstract

A 3-component lacquer composed of A) compounds containing at least two R.sup.1 R.sup.2 C.dbd.CR.sup.3 --X groups (I) wherein R.sup.1 denotes hydrogen or a hydrocarbon radical having 1 to 10 carbon atoms, R.sup.2 and R.sup.3 are individually hydrogen, a hydrocarbon radical having 1 to 10 carbon atoms, an ester group containing the radical R.sup.4 of a monohydric alcohol having up to 12 carbon atoms, --CN, --NO.sub.2 or a --CO--NHR.sup.1 or --CO--R.sup.1 group, X is --CO-- which is attached to a further R.sup.1 R.sup.2 C.dbd.CR.sup.3 -- group either directly or via the radical of a polyhydric alcohol or of an amine and B) compounds containing: PA1 (a) at least two active H atoms or PA1 (b) at least two groups having active H atoms of the type --AH (II) or PA1 (c) at least one active H atom and at least one group of the type (II) and A is --CH-- or --NH-- or --S-- and optionally with customary additives and C) at least one catalyst selected from the group consisting of diazabicyclooctane (DABCO), fluorides of quaternary ammonium compounds on their own or as a mixture with alkyl silicates, amidines, tertiary phosphanes of the formula P(CH.sub.2 --Y).sub.3 in which the Ys are identical …
