Abstract
A coating material for producing a barrier layer on a plastic substrate includes an isocyanate-containing hardener component and a hydroxy-functional binder component. The hydroxy-functional binder component includes an aqueous polymer dispersion which includes a polyphenylene ether or a copolymer of fluorinated ethylene and a vinyl ether, glass hollow bodies, and at least one of an inorganic filler and an inorganic pigment.
