Patent ID: 7910197

Claim:
A multicoat system, on a substrate (A), comprising: a clear coat of at least one radiation-curable coating system (F) comprising at least one polymer selected from the group consisting of urethane (meth)acrylates, epoxy (meth)acrylates, and polyester acrylates, optionally, at least one coat (E), which is pigmented and/or provided with effect substances, and which is adjacent to and under coat (F), said coat comprised of said coating system (F) and optional coat (E) constituting a topcoat, and at least one elastic intercoat (D), which is located between the substrate (A) and the topcoat, and comprises a thermoplastic elastomer, and has a glass transition temperature (T g ) of −20° C. or less (measured in the frequency range up to 1000 Hz), wherein the substrate has an impact strength to DIN EN ISO 179/1fU at 23° C. and 50% humidity of at least 20 kJ/m 2 , and is selected from the group consisting of SAN (styrene-acrylonitrile copolymers), ABS (acrylonitrile-butadiene-styrene-copolymers), and ASA (acrylonitrile-styrene-acrylate copolymers), and physical mixtures thereof, the ratio (V) of the intercoat thickness (ZS) to the total thickness of the intercoat and the topcoat (DL), expressed as V=ZS/(ZS+DL), in the multicoat system, is at least 0.05 at a temperature of at least 25° C. and wherein each coat is coextensive with the substrate.
