Abstract (en)

[origin: WO2012000735A1] The present invention relates to a method for producing a multi-coat colour and/or effect paint system, by (1) applying a pigmented aqueous basecoat material to a substrate, (2) forming a polymer film from the coating material applied in stage (1), (3) applying a clearcoat material to the resulting basecoat film, and subsequently (4) curing the basecoat film together with the clearcoat film. The method of the invention is characterized in that in stage (1) a pigmented aqueous basecoat material is used which comprises at least one ketone of the general formula R1-(C=O)-R2, the ketone being present in an amount of 0.1% to 5% by weight, based on the weight of the coating material, and R1 represents an optionally substituted aliphatic or cycloaliphatic radical having 1 to 10 C atoms, and R2 represents an optionally substituted aliphatic or cycloaliphatic radical having 1 to 10 C atoms, and the sum of the C atoms present in R1 and R2 is at least 5 C atoms.
