TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Composition: The composition further contains stabilizer of organic compound comprising silicon or fluorine in a molecule and/or stabilizer of compound having carbonyl group, hydroxyl group and/or sulfonyl group. Preferred Properties: The acidic catalyst has molecular weight of 173-20000. The content of organic solvent mixed with water is 20 weight parts or more with respect to water (100 weight parts).    TECHNOLOGY FOCUS - POLYMERS - Preferred Compound: The conductive polymer is complex from a dopant such as poly (3,4-dialkoxy thiophene) or poly(3,4-alkylene dioxythiophene) having sulfur-containing repeating unit of formula (I).R1,R2=H, 1-4C alkyl or optionally substituted 1-4C alkylene.Preferred Properties: The content of stabilizer of organic compound is 250 weight parts or less with respect to conductive polymer (100 weight parts). The content of stabilizer of compound having carbonyl group, hydroxyl group and/or sulfonyl group is 10000 weight parts with respect to conductive polymer (100 weight parts). The heat bridging agent has degree of polymerization of 1-1.5, preferably 1-1.1. The solid content of heat bridging agent is 30-5400 weight parts with respect to conductive polymer (100 weight parts). The solid content of acidic catalyst is 500 weight parts or less with respect to conductive polymer (100 weight parts). Preferred Process: The composition for electroconductive coating is coated to a base material and maintained at -20 degrees C to 20 degrees C, preferably -5 degrees C to 10 degrees C to obtain electroconductive coated base material. The electroconductive coated base material has a conductive layer formed by coating, drying and hardening the composition for electroconductive coating to the base material. EXAMPLE - Baytron P (RTM: complex dispersion aqueous solution of poly(3,4-ethylenedioxythiophene)/polystyrene sulfonate with weight average molecular weight of 150000) (in weight parts) (14), Solmix AP-7 (RTM: mixture of ethyl alcohol (85.5 weight%), normal propanol (9.6 weight%) and isopropyl alcohol (4.9 weight%)) (61) and water (25) were mixed to obtain coating composition. A film formed using the coating composition had excellent appearance, total light transmittance of 88% based on JIS K7150, haze of 2.1% based on JIS K7150 and excellent abrasion resistance, solvent resistance, and adhesiveness with respect to base material based on JIS K5400.
