A process for producing moldings, in which a solventborne or aqueous, pigmented coating composition (P) and a free-radically crosslinkable coating composition (K), which after crosslinking to completion produces a transparent coating (KE) are applied to a support sheet, a dried but as yet not completely crosslinked coating (KT) is produced from the coating composition (K), the coated support sheet is shaped and is injection backmolded or foam-backed with a liquid polymeric material, and the coating (KT)-if this has not already taken place-is cured or aftercured; the crosslinkable coating composition (K) comprising a free- radically crosslinkable component (KK) which comprises carbamate and/or biuret and/or allophanate and/or urea and/or amide groups.
