Antistatische Kunststoffteile

摘要

Plastic mouldings with an anti-static finish, for example photographic film substrates, which contain at least two layers on the surface with an antistatic finish, where a layer closer to the plastic surface contains a preparation of a polythiophene built up from structural units of the formula in which R1 and R2, independently of one another, are hydrogen or a C1-C4-alkyl group, or together are an optionally substituted C1-C4-alkylene radical, preferably an optionally alkyl-substituted methylene radical, an optionally C1-C12-alkyl- or phenyl-substituted 1,2-ethylene radical, a 1,3-propylene radical or a 1,2-cyclohexylene radical, and a polyanion, and a more remote layer contains a film-forming polymer and at least one of the two layers contains an alkoxysilane, are distinguished by very good layer adhesion in addition to excellent antistatic properties.
