Multilayer body comprising: 1) a base layer containing * at least one thermoplastic material, * at least one dye selected from the group consisting of structures 1a, 1b: `** Formula ** in which - Ra and Rb independently of each other they represent a linear or branched alkyl or halogen moiety; - n represents independently of the respective R a natural number between 0 and 3, the remainder being n> = 0 hydrogen; and 2a, 2b: ** Formula ** in which - Rc and Rd independently of each other represent a linear or branched alkyl or halogen moiety; - n represents independently of the respective R a natural number between 0 and 3, the remainder being n> = 0 hydrogen; with a light transmission of the base layer of less than 1%, determined according to ISO 13468-2, 2) at least on one side of the base layer a scratch-resistant coating based on polysiloxane with a thickness of 2 at 15 μm, which contains at least one UV absorber, where, provided that the dyes of the structures (1a), (1b), (2a) and (2b) are used individually, these dyes are used in each case in concentrations from 0.05 to 0.50% by weight. |
