Abstract: The present invention relates to a solventborne clearcoat material which comprises at least one additive preparable by reacting at least one alpha,omega-hydroxy-functionalized oligoester which has an OH number of 30 to 160 mg KOH/g, a theoretical carbon-carbon double bond content of 1 to 2.5 mmol/g, a number-average molecular weight of 1000 to 3000 g/mol, and a weight-average molecular weight of 2800 to 10 000 g/mol, and at least one alkoxysilane which possesses an OH-reactive functional group, the sum of the weight percentage fractions of all additives of the invention being 0.5 to 10 wt %, based on the total amount of the solventborne clearcoat material. The present invention further relates to a process for producing multicoat paint systems, and to multicoat paint systems producible by means of said process. The invention further relates to the use of the above-identified additive in solventborne clearcoat materials for the purpose of improving adhesion.
