TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The electroconductive layer comprises a pi -electron conjugated polymer, silver, or a carbon material. The pi -electron conjugated polymer is at least one of polythiophene, polyaniline, polypyrrole or its derivative, preferably poly(3,4-ethylenedioxy)thiophene. The electroconductive layer containing the pi -electron conjugated polymer further comprises polystyrene sulfonic acid as a dopant. The support is a flexible support comprising polyester resin as a main component, which includes polyethylene terephthalate. The adhesive layer comprises an anionic surfactant. The binder resins comprise a polyurethane resin and an acrylic resin, both having a glass transition temperature of greater than or equal to 30 degrees C. The adhesive layer comprises a crosslinking agent, which is a carbodiimide compound. The mass ratio of the polyurethane resin to the acrylic resin (polyurethane resin:acrylic resin) is 95:5-50:50. The thickness of the adhesive layer is 30-200 nm. The adhesive layer comprises organic or inorganic fine particles and a sliding agent. The adhesive layer is formed by coating an aqueous coating liquid for forming an adhesive layer and drying the coating liquid at a maximum temperature of 120-170 degrees C. EXAMPLE - Polyethylene terephthalate resin (PET) was dried until the water content in it was 50 ppm or lower, and then melted in an extruder at 280-300 degrees C. The melt of PET resin was ejected through a die onto a chilled roll charged electrostatically. The resulting amorphous base was drawn by 3.3 times in the running direction of the base and further drawn by 3.8 times in the width direction to obtain the support having 188 mu m thickness. The support was transported at 80 m/minute. The composition of the coating liquid (comprised (in parts by mass): Olester ud350 (RTM: Urethane resin binder) (30.7); AS563 (RTM: Acrylic resin binder) (4.2); Carbodilitev-02-l2 (RTM: Multifunctional polycarbodiimide crosslinking agent) (5.8); Aerosil ox-50 (RTM: Hydrophobic fumed silica) (1.9); Snowtex xl (RTM: Colloidal silica) (1.8); Cellosol 524 (RTM: Carnauba wax dispersion) (1.9); 1 mass% of aqueous solution of Lapisol a-90 (RTM: Surfactant) (15.5); 1 mass% aqueous solution of Naroacty cl-95 (RTM: Surfactant) (19.4); and distilled water) was added to the support to make the total composition 1000 parts by mass. The coating liquid was coated on the both faces in a coating amount of 4.4 cm3/m2 by bar coating method. Adhesive layers were formed by drying at 160 degrees C for 1 minute. Denatron p502 (RTM: Aqueous dispersion liquid) containing poly(3,4-ethylenedioxy)thiophene doped with polystyrene sulfonic acid was coated with a coater onto the face of the PET film having the adhesive layer on them, and dried to obtain electroconductive polymer material.
