Abstract

The invention relates to trims for motor vehicle glazing systems, comprising a base layer and a coating and having glass-like optical properties at least in some subsections, composites consisting of such trims for motor vehicle glazing systems, and car body parts, as well as preferred embodiments which comprise suitable combinations of materials. Said trims comprising, at least towards the front side thereof, an edge rounding having a variable radius which allows a more uniform layer thickness for the coating.
