The invention relates to a method for producing moulded parts. The method comprises the following step: a pigmented covering agent (P), which is aqueous or contains a solvent, is applied to a carrier film and a radically cross-linkable coating agent (K) which provides a transparent covering (KE) after final cross-linking; a dried, but not finally cross-linked coating (KT) is produced from the coating agent (K); the coated carrier film is formed and is rear-injected or foamed from behind by means of a liquid plastic material; and the coating (KT) is allowed to cure or post-cure if it has not already done so. According to the invention, the cross-linked coating agent (K) contains a radically cross-linkable component (KK) which contains the carbamate and/or biuret and/or allophanate and/or urea and/or amide groups.
