Cuerpo multicapa que comprende: 1) una capa de base que contiene * al menos un material termpolástico, * al menos un colorante seleccionado del grupo que consiste en las estructuras 1a, 1b:`**Fórmula** en las que - Ra y Rb independientemente entre sí representan un resto alquilo lineal o ramificado o halógeno; - n representa independientemente del R respectivo un número natural entre 0 y 3, siendo el resto para n >= 0 hidrógeno; y 2a, 2b:**Fórmula** en las que - Rc y Rd independientemente entre sí representan un resto alquilo lineal o ramificado o halógeno; - n representa independientemente del R respectivo un número natural entre 0 y 3, siendo el resto para n >= 0 hidrógeno; con una transmisión de luz de la capa de base inferior al 1 %, determinada según la norma ISO 13468-2, 2) al menos en un lado de la capa de base un recubrimiento resistente al rayado a base de polisiloxano con un grosor de 2 a 15 μm, que contiene al menos un absorbedor UV, n donde, siempre que los colorantes de las estructuras (1a), (1b), (2a) y (2b) se empleen individualmente, estos colorantes se emplean en cada caso en concentraciones del 0,05 al 0,50 % en peso. The present invention relates to dark multilayer bodies made from polycarbonate, which are characterised by a glass-like deep-gloss effect on the surface. The invention also relates to a method for producing these multilayer bodies. The multilayer bodies are preferably synthesised from polycarbonate or polycarbonate blends. The polycarbonate blends can contain further polymers such as for example elastomers or graft polymers, or further thermoplastics such as polyesters for example. The invention also relates to the use of the multilayer bodies according to the invention as panels for vehicle parts or as frame parts for multimedia housings.
