  • the coating is preferably designed such that it can be irradiated with light from the inner layer side or with light from the base body.
  • the coating is preferably designed such that it reflects light from the outer layer side or light from the side facing away from the base body side. The reflection can take place completely, or substantially completely, or at least partially.
  • the coating is thus advantageously partially transparent, wherein it is formed from the outside reflecting and can be irradiated from the inside with light from a light source of a lamp.
  • This solution has the advantage that the element can be used, for example, as an emblem for a vehicle manufacturer. Here, it can be irradiated from the vehicle via the main body with light from the light source to illuminate the element, especially at night. If the element is not illuminated, the reflective coating results in the element appearing like a common emblem of a vehicle manufacturer.
  • the coating is designed such that it reflects metallic and / or shiny. As a result, an aesthetic appearance of the coating, in particular of a typically metallic and glossy emblem of a vehicle manufacturer, is adaptable. Thus, the element "shiny from the front" shiny metallic and "from behind” be irradiated with the light from the light source.

  • the primer layer has the advantage that it increases the resistance of the element to thermo-mechanical stresses between the base body and the coating or the silver layer. Furthermore, the primer layer can compensate for unevenness of a surface of the base body and thus increase an aesthetic appearance of the element. Furthermore, the adhesion promoter layer as a diffusion barrier for gases such.

  • a thickness of the partially or completely made of chromium adhesive layer is less than or equal to 5 nm. Furthermore, it is advantageous if the partially or completely made of chromium primer layer is formed as seeding.

Further preferably, the base body consists of a thermoplastic material. It would also be conceivable to use injection-moldable thermosets, which are characterized by good dimensional stability.
  • the base body is thus preferably a transparent plastic, which is illuminated by a light source and partially or completely serves as a light pipe.
