Abstract

A formulation comprising PA1 a) at least one polythiophene in oxidised polycationic form and containing structural repeating units of formula I ##STR1## wherein R.sub.1 and R.sub.2 are each independently of the other linear or branched C.sub.1 -C.sub.18 alkyl or C.sub.2 -C.sub.18 alkoxyalkyl; or are C.sub.3 -C.sub.8 cycloalkyl, phenyl or benzyl which are unsubstituted or substituted by C.sub.1 -C.sub.6 alkyl, C.sub.1 -C.sub.6 alkoxy or halogen; or R.sub.1 and R.sub.2, taken together, are linear C.sub.1 -C.sub.8 alkylene which is unsubstituted or substituted by C.sub.1 -C.sub.6 alkyl, C.sub.1 -C.sub.6 alkoxy, halogen, C.sub.3 -C.sub.8 cycloalkyl, phenyl, benzyl, C.sub.1 -C.sub.4 alkylphenyl, C.sub.1 -C.sub.4 alkoxyphenyl, halophenyl, C.sub.1 -C.sub.4 alkylbenzyl, C.sub.1 -C.sub.4 alkoxybenzyl or halobenzyl; and PA1 b) at least one polyanion of a film-forming thermoplastic polymer containing sulfated alcohol groups ##STR2## and/or sulfonatoalkylated alcohol groups ##STR3## in structural repeating units, wherein the group --(C.sub.n H.sub.2n)-- is linear or branched C.sub.2 -C.sub.12 alkylene which contains 2 to 5 carbon atoms in the carbon chain and is unsubstituted or substituted by…
