Abstract
An aqueous dispersion is described which contains electroconductive, doped, polyalkoxythiophene which is soluble in aprotic organic solvents and is insoluble in water. The dispersion has a residual solvent content of less than or equal to 25% by weight, based on the total weight of the dispersion. A process for the preparation of this dispersion and the use of the dispersion for forming coatings on substrates are also described.
