<P>PROBLEM TO BE SOLVED: To provide a conductive ink, whose solubility or the dispersibility to a solvent including an organic solvent is excellent, that excels in processability and is useful as a transparent electrode material or the like which has high conductivity and transparency, and that can be used for ink jet printing. <P>SOLUTION: A conductive ink is characterized in that a random copolymer of a dithienopyrrole compound that may be substituted by an alkyl group or an alkoxy group and a thiophene compound that may be substituted by an alkyl group or an alkoxy group, and a dopant of a transition metal salt or the like are dispersed or dissolved in a solvent. The copolymer included in the conductive ink is manufactured by a chemical oxidation polymerization method under the existence of an oxidizing agent and a surfactant. <P>COPYRIGHT: (C)2013,JPO&INPIT |
