Abstract

Plastic articles esp. lenses of automobile rear lights which are divided into several zones with a different permeability to colour, are produced by (a) injection moulding the article in a material with a lower permeability to light, such as orange or red, and (b) injection moulding over this article a base or connecting piece extending over all the zones in a material with a max. permeability to light e.g. having the clearness of glass. Separate pieces of different colours are pref. prefabricated by successive injection moulding operations, or by a single injection.
