Abstract

The invention relates to a coating material that can be cured thermally or by actinic radiation and that contains at least one component (a1) with at least two functional groups (a11) which serve for cross-linking, by actinic radiation, and at least one functional group (a12) that can enter into thermal cross-linking reactions with the hydroxyl and/or thiol groups (a21) in component (a2), at least one branched cyclic and/or acyclic C9-C16 alkane (a2)) that is functionalized with at least two hydroxyl or thiol groups (a21) or with at least one hydroxyl and at least one thiol group, and optionally at least one photo initiator (a3), at least one initiator of the thermal cross-linking reaction (a4), at least one reactive diluent that is cured by actinic radiation and/or thermafly, at least one lacquer additive (a6), at least one thermally curable component (a7) and/or at least one organic solvent (a8). The inventive coating material is used to produce transparent lacquers and multi-layer chromophor and/or effect lacquers.
