Scratch-resistant conductive coatings
摘要:
Mixture of a polythiophene preparation which contains a polythiophene salt polythiophene.sup..sym. An.sup..crclbar. in which the polythiophene contains positively charged and uncharged recurring units of the formula ##STR1## in which R.sub.1 and R.sub.2 independently of one another stand for hydrogen or a C.sub.1 -C.sub.4 alkyl group or together form an optionally substituted C.sub.1 -C.sub.4 alkylene radical, preferably a methylene radical optionally substituted with alkyl groups, an ethylene-1,2 radical optionally substituted with C.sub.1 -C.sub.12 alkyl groups or phenyl groups, a propylene-1,3 radical or a cyclohexylene-1,2 radical, andAn.sup..crclbar. 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.
