摘要

A 3-component lacquer composed of A) compounds containing at least two R1R2C=CR3-X groups (I) wherein R1 denotes hydrogen or a hydrocarbon radical having 1 to 10 carbon atoms, R2 and R3 are individually 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, X is -CO- which is attached to a further R1R2C=CR3- group either directly or via the radical of a polyhydric alcohol or of an amine and B) compounds containing: (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) 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(CH2-Y)3 in which the Ys are identical or different and are -OH, -CH2CN or -N(Z)2 in which Z is an alkyl having 1 to 5 carbon atoms, tertiary phosphanes of the formula P(R4,R5,R6) in which R4, R5 and R6 are alkyl of 1 to 12 carbon atoms or a phenyl which is unsubstituted or substituted by at least one alkyl, alkoxy or dialkylamino, each of which has 1 to 4 carbon atoms in the alkyl, and R4, R5 and R6 are identical or different, but at least one of them is phenyl, and aminophosphoranes of the formula (R7,R8,R9) P=N-C (R10, R11,R12) in which R7, R8 and R9 are identical or different and denote an alkyl having 1 to 12 carbon atoms or a alkoxy or dialkylamino group, each of which has 1 to 4 carbon atoms in the alkyl, and R10, R11 and R12 are identical or different and each represents an alkyl having 1 to 5 carbon atoms or a phenyl.
