METHOD FOR PRODUCING A COLOR- AND/OR EFFECT-PRODUCING MULTILAYER COATING, IN WHICH THE COLOR-FORMING COATING COMPOUND CONTAINS A SUBSTITUTED CYCLOHEXANOL IN ORDER TO REDUCE THE NUMBER OF PINHOLES

摘要

The invention relates to a method for producing a color- and/or effect-producing multilayer coating, wherein (1) a pigmented aqueous base coating is applied onto a substrate, (2) a polymer film is formed from the coating that is applied in step (1), (3) a clear coating is applied onto the base coating layer that is thus obtained, and then (4) the base coating layer is cured together with the clear coating layer. The method according to the invention is characterized in that a pigmented aqueous base coating is used in step (1), said base coating containing at least one cyclohexanol that is substituted in the 2- and 5-position and/or at least one cyclohexanol that is substituted in the 3- and 5-position and/or at least one monosubstituted cyclohexanol. The substituents are optionally branched alkyl groups with 1 to 5 C atoms and can consist of a bridged isopropylene group in the case of a substitution in the 2- and 5-position. The substituted cyclohexanol or the mixture of substituted cyclohexanols is present in a quantity of 0.1 to 5 wt.% with respect to the weight of the aqueous base coating that is applied in step (1).
