The present invention relates to a coating composition comprising (a) at least one thermoplastic polymer having a mean molar mass Mw of at least 100 000 g/mol in a content of at least 30% by weight of the solids content of the coating composition, (b) at least one UV-curable reactive diluent in a content of at least 30% by weight of the solids content of the coating composition, (c) at least one photoinitiator in a content of ≥ 0.1 to ≤ 10 parts by weight of the solids content of the coating composition, and (d) at least one organic solvent, where the proportion of ethylenically unsaturated groups is at least 3 mol per kg of the solids content of the coating composition. It further relates to a process for producing such coating compositions, to films coated therewith, to the use of such films for production of shaped bodies, to a process for producing shaped bodies having a radiation-cured coating, and to shaped bodies producible by this process. The inventive coatings have excellent solvent stability, and good scratch resistance and pencil hardness. |
