- Patent Document 2 a method for producing a ⁇ -conjugated conductive polymer colloid aqueous solution by chemical oxidative polymerization in the presence of polyacrylic acid has been proposed (see Patent Document 2).
- an aqueous dispersion solution containing a ⁇ -conjugated conductive polymer can be easily produced.
- a large amount of polyone is contained in order to ensure the dispersibility of the ⁇ -conjugated conductive polymer in water. Therefore, the obtained conductive composition contains many compounds that do not contribute to conductivity, and there is a problem that high conductivity is difficult to obtain.
- the resin film is an insulator as it is, it is easily charged by being charged or immediately rubbed. Moreover, the static electricity accumulates in a way that escapes to the outside, causing various problems.
- the optical filter and the optical information recording medium are required to have a surface having high hardness and high transparency, and to have antistatic properties in order to prevent dust from adhering due to static electricity.
- the antistatic property is required to have a stable resistance value (that is, a stable antistatic property) in the region where the surface resistance is 10 6 to 10 1 (> ⁇ ).

- the coating film may be severely cracked and may not exhibit conductivity.
- peeling may occur at the interface between them and the transparency may be lowered.
- ⁇ -conjugated conductive polymers are known as organic materials having electronic conduction as a conduction mechanism, but ⁇ -conjugated conductive polymers generally have insoluble and infusible properties and are polymerized. It was difficult to apply on a film substrate later. Therefore, a mixture obtained by polymerizing arrin in the presence of a polymer acid having a sulfo group (polyarone) to form water-soluble polyarlin was coated on a film substrate and dried. Attempts have been made (see, for example, Patent Document 3).
- an antistatic film can be formed by direct polymerization on a substrate, but in that case, the antistatic film has low conductivity and is water-soluble. As a result, the adhesion to the base material made of resin is low, and the manufacturing process becomes complicated.

- the solid electrolyte layer of a capacitor is a layer composed of a ⁇ -conjugated conductive polymer such as pyrrole or thiophene, penetrates into the porous body, and comes into contact with a larger-area dielectric layer to increase the capacitance. It plays the role of preventing leakage current by repairing the missing part of the dielectric layer.
- the polymerization time is long, and it is necessary to repeat the polymerization in order to ensure the thickness, so that the production efficiency of the capacitor is low and the conductivity is also low.
- Patent Document 7 describes the preparation of water-soluble polyaline by polymerizing arlin in the presence of a polymer acid having a sulfo group, a force-loxy group, etc., and the polyaline aqueous solution on the dielectric layer. The method of applying and drying is described.
- this production method is simple, the permeability to the inside of the porous body is inferior, and since the polymer acid is included in addition to the ⁇ -conjugated conductive polymer, the conductivity is low. In some cases, the electrical conductivity is dependent on humidity due to the influence of acid.
