Beschreibung
Zusammenfassung:	The invention relates to a method for the surface finishing of plastic substrates, preferably polymethyl methacrylate (hereinafter PMMA for short), by coating with a clear, nanoparticle-containing coating agent (nanocomposite coating agent hereinafter) and irradiation thereof with vacuum UV light with a wavelength of 172 nm from an Xe* excimer lamp. This method results in excellent adhesion of the coating material to the substrate. Furthermore, the generation of a topography of the coating surface is made possible. The mechanical, chemical and performance properties of uncoated substrate are substantially exceeded by a substrate coated in this way.
