| 摘要 |
The invention relates to a method for producing a multilayer clearcoat, especially used in color- and/or effect-imparting multilayer coats, by applying a first clearcoat, drying the resulting first clearcoat layer without curing it, or, alternatively, curing the first clearcoat layer, applying a second clearcoat that differs in terms of composition from the first clearcoat and curing the first and the second clearcoat layer together, or, alternatively, curing the second clearcoat layer separately. The second clearcoat contains (A) as a binder a siloxane-group free (meth)acrylate copolymer that contains, based on the siloxane-group free (meth)acrylate copolymer, up to 90 wt.- % of hydroxy-group containing monomers polymerized into it. 10 to 90 wt.- % of these monomers are 4-hydroxybutyl(meth)acrylate and/or 2-alkyl-propane-1,3-diol-mono(meth)acrylate and 0 to 45 wt.- % or other hydroxyl-group containing monomers. The second clearcoat further contains (B) tris(alkoxycarbonylamino)triazine as the cross-linking agent, and the first and second clearcoats do not contain tricyclodecane dimethanol (TCD).
