发明名称 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 Disclosed is a method for producing a multicoat color and/or effect painting system by applying a pigmented aqueous basecoat material to a substrate, forming a film from the applied coating, applying a clearcoat material to the film, and then curing the film together with the clearcoat material, wherein the pigmented aqueous basecoat material comprises at least one substituted cyclohexanol in an amount of 0.1% to 5% by weight, based on the weight of the pigmented aqueous basecoat material, the substituted cyclohexanol being selected from the group consisting of a cyclohexanol substituted in positions 2 and 5, a cyclohexanol substituted in positions 3 and 5, a monosubstituted cyclohexanol, and mixtures of two or more of the foregoing, wherein the substituents are selected from the group consisting of optionally branched alkyl groups having 1 to 5 C atoms, a bridging isopropylene group and mixtures of two or more of the foregoing.
