Abstract
Abstract Mixture of a polythiophene preparation which contains a polythiophene salt polythiophene(+) An(-) in which the polythiophene contains positively charged and uncharged recurring units of the formula in which R1 and R2 independently of one another stand for hydrogen or a C1-C4 alkyl group or together form an optionally substituted C1-C4 alkylene radical, preferably a methylene radical optionally substituted with alkyl groups, an ethylene-1,2 radical optionally substituted with C1-C12 alkyl groups or phenyl groups, a propylene-1,3 radical or a cyclohexylene-1,2 radical, and An(-) denotes a polyanion, and coating compositions which are curable by ionising radiation, and the use thereof in order to produce scratch-resistant electrically conductive coatings.
