Conductive film

摘要

A conductive film which is excellent in moist heat resistance, conductivity, transparency and coating film strength. The conductive film comprises a base film and a coating layer formed on the base film by curing a composition comprising:
(i) a conducting polymer containing a polycationic polythiophene having a recurring unit represented by the following formula (1) as the main constituent and a polyanion (component A) :
wherein R 1 and R 2 are each independently a hydrogen atom or alkyl group having 1 to 4 carbon atoms or bonded together to form an alkylene group having 1 to 12 carbon atoms which may be substituted arbitrarily;
(ii) a water-soluble compound having at least one hydrophilic group selected from the group consisting of oxyethylene group and sulfonate group (component B); and
(iii) a crosslinking agent having a glycidyl group (component C), and
which has a surface resistance change rate after it is treated at a temperature of 60°C and a humidity of 90 % for 240 hours of 160 % or less.
