Abstract
The invention relates to a coating material which can be hardened thermally and, optionally, by using actinic radiation. Said coating material contains: A) a binding agent comprising at least two functional groups (a1) which can enter into thermal cross-linking reactions with complementary functional groups (b1) in cross-linking agent (B), and; (B) at least one cross-linking agent comprising at least two functional groups (b1) which can enter into thermal cross-linking reactions with complementary functional groups (a1) in binding agent (A). At least one binding agent (A) contains, in an integrally polymerized manner, at least one olefinically unsaturated polysiloxane macromonomer which contains, in the statistical mean, at least 3.0 double bonds per molecule. The invention also relates to the use of the coating material for producing highly scratch resistant multilayer transparent lacquers.
