摘要:
The present invention relates to multicoat paint systems comprising basecoats and clearcoats with high solids fractions that each comprise at least one sulfonic acid compound of formula (I) or formula (II). The invention further relates to a method of producing these multicoat paint systems and to their use, and also to substrates coated with the multicoat paint system. The invention relates, furthermore, to the use of the sulfonic acid compounds of formula (I) and formula (II) in basecoats and clearcoats with high solids fractions.
