FIELD: chemistry.
SUBSTANCE: description is given of the method of obtaining a water dispersion containing a complex of poly(3,4-dialkoxythiophen) and polyanion, including polymerisation of 3,4-dialkoxy-thiophen, with general formula (I): where R1 and R2 independently represent a hydrogen atom or alkyl with 1-4 atoms of carbon, or together form an alkylene group with 1-4 carbon atoms, which can be substituted in the presence of polyanion with use of peroxodisulphuric acid as an oxidiser in a water solution with pH equal to or less than 1.5, or use of an oxidiser in a water solution, in which acid has been added, chosen from a group, consisting of water soluble inorganic acids and water soluble organic acids, in quantity providing for pH of the obtained reaction mixture equal to 1.5 or less. Description is also given of the composition of the coating, containing water dispersion which contains the complex of poly(3,4-dialkoxythiophen) and polyanion. The substrate with a conducting transparent film, obtained through deposition of the above given composition is also described.
EFFECT: obtaining of water dispersion, providing the coating obtained from it with lower surface resistivity.
