    摘要: A process for producing moldings, in which a 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 contains hydrogen bond forming structural elements in an amount such that 1. a coating (MT) produced from the mixture (M) of component (KK) with additives, but as yet not crosslinked to completion, has a ratio of storage modulus G(MT)′ to loss modulus G(MT)″ of from 5 to 200, G(MT)′ and G(MT)″ having been determined at 20° C. by means of rheological oscillation measurements, and 2. a coating (ME) produced from the mixture (M) of component (KK) with additives and crosslinked to completion has a storage modulus E(ME)″ of from 1.0*107.0 to 8.0*107.0 Pa, E(ME)′ having been measured in the rubber-elastic range by dynamic mechanical thermal analysis.
