44 Coating composition suitable for use in the production of coatings with a rapidly curable surface containing A) 10 - 80 wt.% of one or more compounds with on average at least two CH-acid hydrogen atoms, B) 10 - 80 wt.% of one or more .alpha.,.beta.-unsaturated compounds with at least two identical or different groups of the general formula R1R2C=CR3-CO- which are linked together by the residue of a di-or polyhydric alcohol, a di- or polyamine or aminoalcohol, in which R1, R2 and R3 are mutually independently a hydrogen atom or a straight or branched alkyl residue with 1 to 10 carbon atoms, which residue may be olefinically mono- or polyunsaturated and/or may have one or more hydroxyl groups, C) 0 - 50 wt.% of one or more radically or ionically polymerisable compounds, D) 5 - 50 wt.% of one or more polyamines with at least two amine functional groups, related to the sum of the weights of A), B) and C, which may be primary and/or secondary and which may be entirely or partially capped, per molecule, E) 0.01 - 5 wt.%, related to the sum of the weights of components A), B), C) and D) of a catalyst in the form of one or more Lewis or Br?nsted bases, wherein the conjugate acids of the latter have a pKA value of at least 10, F) 0.1 to 10 wt.%, related to the sum of the weights of components A), B), C) and D) of one or more photoinitiators, together with pigments and/or extenders, optionally together with auxiliary substances and additives customary in lacquers and optionally one or more organic solvents and/or water.
