    摘要: The invention relates to a multilayer product containing a first layer (S1) and a second layer (S2). The first layer is a lacquer obtained from A) one or more aliphatic polymer precursors selected from among at least one of the groups comprising components A.1 and A.2, wherein A.1) represents aliphatic oligomers that contain urethane or ester bonds and have at least two acrylate functions per molecule, or mixtures of corresponding oligomers, and A.2) represents aliphatic reactive diluents having at least two acrylate groups per molecule, or mixtures of corresponding reactive diluents, B) one or more fine-particle inorganic compounds, C) at least one organic UV absorber selected from among the group of triazine derivatives and diphenyl triazine derivatives, D) 0.1 to 2 wt. %, relative to the experimentally determined solid content of the mixture of components A, B, and F, of a radical interceptor belonging to the class of basic HALS, E) one or more optional self-leveling agents, F) one or more optional solvents, and G) at least one Norrish type II photoinitiator. The second layer is a thermoplastic polymer. The invention also relates to a lacquer made of the aforementioned components.
