摘要

Production of permanent light-refracting, light-scattering, light-absorbing, light-coloring and light-producing structures on or in ethylene-tetrafluoroethylene copolymers comprises applying passive or active pigments as e.g. lacquer to a corresponding prepared carrier film, and fixing with a covering film or embossing the structures in the surface.
