A highly scratch-resistant multicoat paint system on a primed or unprimed substrate, comprising above one another in this order(A) a basecoat,(B) a first clearcoat as intermediate coat, and(C) a second clearcoat as the topmost coat, wherein the second clearcoat (C) is producible from a coating coating material(C) comprising(C1) at least one oligomer and/or polymer containing at least one pendant carbamate and/or allophanate group (c11), especially carbamate group (c11), of the formula:and(C2) at least one crosslinking agent containing at least two functional groups (c21) which undergo crosslinking reactions with the carbamate group and/or allophanate group (c11);and also a process for producing highly scratch-resistant multicoat systems.
