PROBLEM TO BE SOLVED: To provide an antistatic coating composition, capable of forming a coating film good at adherence to plastic substrates, high in water resistance, electroconductivity and transparency. SOLUTION: This composition is obtained by compounding an electroconductive polymer comprising a poly(3,4-disubstituted thiophene) and a polyanion, a water-soluble compound having amido group or hydroxy group and liquid at normal temperature and a self-emulsifiable polyester resin aqueous dispersion at a specified ratio. The composition is capable of forming a coating film excellent in adhesion, transparency, electroconductivity, solvent resistance and, especially, water resistance. Both the water resistance and solvent resistance of the resulting coating film are further increased by compounding this composition with a specified amount of an alkoxysilane having epoxy group.
