Abstract:
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 R1 and R2 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.
