摘要： The present invention relates to a multi-layer body comprising in this order, (I) a substrate layer made of a specific thermoplastic polycarbonate molding compound, (II) at least one layer made of a colorant or a colorant composition and (III) a film. The present invention also relates to a lighting unit, comprising the multi-layer body and a light source, to a method for producing the multi-layer body, and to the use of the specific thermoplastic polycarbonate molding compound as a substrate layer of a multi-layer body of this type.

摘要： The present invention relates to LED lighting elements comprising translucent mouldings composed of polycarbonate-based moulding compounds, comprising a colourant mixture, carbon black, scattering additive and optionally white pigment, as used, for example, as covers with a day/night design. Through combination with one or more RGB-LEDs, it is possible to achieve surprising colour effects in night design with presence of a deep gloss effect in mouldings that are black and grey in day design.
