    摘要： The invention relates to coating agent compositions, containing: a) at least one component (A) containing polyhydroxyl groups, b) at least one component (B) having on average at least one isocyanate group and on average at least one hydrolysable silane group of formula (I): -NR-(X-SiR''x(OR')3-x) and/or at least one hydrolysable silane group of formula (II): -N(X-SiR''x(OR')3-x)n(X'-SiR''y(OR')3-y)m, c) at least one catalyst (D) containing phosphorous and nitrogen, for crosslinking silane groups, and d) at least one catalyst (Z) for reacting hydroxyl groups with the isocyanate groups, characterised in that i) the catalyst (Z) is selected from the group consisting of zinc and bismuth carboxylates, aluminium, zirconium, titanium and/or boron chelates and/or inorganic catalysts containing tin, and mixtures thereof, and ii) the coating agent composition contains at least one reaction accelerator (R) selected from the group consisting of inorganic acids and/or organic acids and/or partial esters of the inorganic acids and/or partial esters of the organic acids. The invention also relates to methods for producing multi-layered paintwork using the coating agent compositions, to the coatings obtainable using the method, and to the use of same.
