Described is a method for producing a multicoat color and/or effect paint system by (1) applying to a substrate a pigmented aqueous basecoat material, (2) forming a polymer film from the coating material applied in stage (1), (3) applying a clearcoat material to the resultant polymer film, and then (4) curing the polymer film together with the clearcoat film. The pigmented aqueous basecoat material comprises at least one alcohol having a structure: wherein R is a C1 to C4 alkyl radical, with the proviso that R is not an n-butyl radical. The at least one alcohol is used in an amount of 0.1% to 5% by weight, based on the total weight of the aqueous basecoat material. Additionally, described are the corresponding coating materials and also the use of the alcohols in pigmented aqueous coating materials.
