Title:
CONDUCTIVE FILM
Document Type and Number:
WIPO Patent Application WO/2008/029933
Kind Code:
A1
Abstract:
Disclosed is a conductive film which is excellent in wet heat resistance, electric conductivity, transparency and coating film strength. Specifically disclosed is a conductive film wherein a coating film layer is arranged on a base film, which coating film layer is obtained by curing a composition containing (i) a conductive polymer (component A) containing a polycation-like polythiophene mainly composed of a repeating unit represented by the formula (1) below and a polyanion; (ii) a water-soluble compound (component B) having at least one hydrophilic group selected from the group consisting of an oxyethylene group and a sulfonate group; and (iii) a crosslinking agent (component C) having a glycidyl group. In this conductive film, the change rate of the surface resistance after a 240-hour treatment at a temperature of 60˚C and a humidity of 90% is not more than 160%. In the formula, R1 and R2 independently represent a hydrogen atom or an alkyl group having 1-4 carbon atoms, or alternatively R1 and R2 may combine together and form an optionally substituted alkylene group having 1-12 carbon atoms.
