Abstract
A conducting varnish composition consisting essentially of: PA1 (a) a tetracyanoquinodimethane complex salt; PA1 (b) a high molecular weight compound; PA1 (c) PA2 (i) at least one compound selected from the group consisting of acetals, orthoformic acid esters, orthoacetic acid esters, orthocarbonic acid esters, siloxanes, silyl ethers and orthosilicic acid esters; and/or PA2 (ii) a surfactant or a silicone oil; and PA1 (d) a solvent. the TCNQ complex salt is stable in a solution of the composition according to the present invention and the composition can be stored for a long period of time. Therefore, it provides a conducting material which exhibits a constant conductivity. Also, the composition of the present invention is excellent in the film-formability and moldability, and can be formed into a film or an article of good quality, that is, having no incomplete part.
