Abstract
Disclosed is a method for producing a multicoat color and/or effect paint system, comprising (1) applying a pigmented aqueous basecoat to a substrate, (2) forming a polymer film from the basecoat applied in stage (1), (3) applying a clearcoat to the polymer film, and then (4) curing the polymer film together with the applied clearcoat to form a clearcoat film. The pigmented aqueous basecoat comprises at least one ester characterized by the following structure: where Ris selected from the group of ethyl and isopropyl and Ris a Cto Cradical. The at least one ester is used here in an amount of 0.1% to 5% by weight, based on the total weight of the aqueous basecoat applied in stage (1). The invention further provides the corresponding coating materials and the use of the esters in pigmented aqueous coating materials.
