Method for producing materials-plastic composites, wherein a layer of a coating material is applied to at least one materials component, filmed and (partially) crosslinked, - where the (partially) crosslinked coating material has (re-)active free isocyanate groups and/or epoxy groups and/or isocyanate groups deblockable with thermal redissociation and/or (thermally and/or catalytically) activatable uretdione groups and/or allophanate groups and/or biuret groups, and subsequently at least one elastic plastics component is applied in the liquid-melt state at least partially to the (partially) crosslinked coating film by means of a thermal application method, where the plastics component has functional groups which are capable in the liquid-melt state of entering, with the (re-)active and/or (thermally and/or catalytically) activatable groups of the (partially) crosslinked coating material, into a covalent bond in the form of urethane groups and/or allophanate groups and/or urea groups and/or biuret groups and/or ester groups and/or ether groups and/or amide groups and/or amine groups, or - where the (partially) crosslinked coating material has functional groups in the form of epoxy groups and/or hydroxyl groups and/or carboxyl groups, and subsequently at least one elastic plastics component is applied in the liquid-melt state at least partially to the coating film by means of a thermal application method, where the plastics component has free and/or thermally deblockable isocyanate groups and/or uretdione groups and/or allophanate groups and/or biuret groups and/or epoxy groups which are capable in the liquid-melt state of entering into a covalent bond with the functional groups of the (partially) crosslinked coating material, and where the coating material, after the application of the elastic plastics component and during the entire further processing to form materials-plastic composites, is not melted and the composite is not thermally aftertreated. - where the (partially) crosslinked coating material has (re-)active free isocyanate groups and/or epoxy groups and/or isocyanate groups deblockable with thermal redissociation and/or (thermally and/or catalytically) activatable uretdione groups and/or allophanate groups and/or biuret groups, and subsequently at least one elastic plastics component is applied in the liquid-melt state at least partially to the (partially) crosslinked coating film by means of a thermal application method, where the plastics component has functional groups which are capable in the liquid-melt state of entering, with the (re-)active and/or (thermally and/or catalytically) activatable groups of the (partially) crosslinked coating material, into a covalent bond in the form of urethane groups and/or allophanate groups and/or urea groups and/or biuret groups and/or ester groups and/or ether groups and/or amide groups and/or amine groups, or - where the (partially) crosslinked coating material has functional groups in the form of epoxy groups and/or hydroxyl groups and/or carboxyl groups, and subsequently at least one elastic plastics component is applied in the liquid-melt state at least partially to the coating film by means of a thermal application method, where the plastics component has free and/or thermally deblockable isocyanate groups and/or uretdione groups and/or allophanate groups and/or biuret groups and/or epoxy groups which are capable in the liquid-melt state of entering into a covalent bond with the functional groups of the (partially) crosslinked coating material,
