Abstract
An aqueous composition containing a polymer or copolymer of a 3,4-dialkoxythiophene in which the two alkoxy groups may be the same or different or together represent an optionally substituted oxy-alkylene-oxy bridge, a polyanion and a non-Newtonian binder; a method for preparing a conductive layer comprising: applying the above-described aqueous composition to an optionally subbed support, a dielectric layer, a phosphor layer or an optionally transparent conductive coating; and drying the thereby applied aqueous composition; antistatic and electroconductive coatings prepared according to the above-described method for preparing a conductive layer; a printing ink or paste comprising the above-described aqueous composition; and a printing process comprising: providing the above-described printing ink; printing the printing ink on an optionally subbed support, a dielectric layer, a phosphor layer or an optionally transparent conductive coating.
