Abstract

A method for producing a polymeric conductive layer on an object comprising the steps of: PA1 providing an aqueous composition containing a polythiophene, a polyanion compound and an aprotic compound with a dielectric constant, .epsilon., .gtoreq.15, PA1 applying said composition to said object forming a layer and PA1 drying said layer to form a conductive polymeric layer on said object, characterised in that during said production said object and said layer are kept at a temperature below 100.degree. C. and said conductive polymeric layer has a resistivity of at most 2 k.OMEGA./square.
