Abstract (en)

[origin: WO2004114326A1] An aqueous dispersion of latex particles, said latex particles containing a polymer containing monomer units according to formula (I), in which R<1> and R<2> independently of one another represent hydrogen or a C1-5-alkyl group or together form an optionally substituted C1-5-alkylene residue and at least one polyanion compound, said latex having a primary particle size of less than 40 nm and said dispersion contains an organic compound containing a di­or polyhydroxy- and/or carboxy groups or amide or lactam group or an aprotic compound with a dielectric constant, ɛ, >= 15, characterized in that said latex particles contain said at least one polyanion compound and said polymer in a weight ratio of at least 4; a process for preparing an electroconductive coating comprising the steps of: preparing an aqueous solution or dispersion of the abovementioned polymer by polymerization with an initiator in a reaction medium in the presence of at least one polyanion compound under oxidizing or reducing conditions.
