Abstract:
1. A conductive composition for a solid electrolyte capacitor comprising a conductive polymer (A) for the solid electrolyte capacitor; a basic compound (B); and a solvent (C); wherein the conductive polymer (A) for the solid electrolyte capacitor contains substituted polythiophene (P) comprising thiophene repeating units (D) wherein the hydrogen atoms at position 3 and/or position 4 of the thiophene ring of the repeat unit are substituted by at least one type of group (s) selected from a group made up of: (a) a polyether group (a) indicated by the following general formula (1): where OR 1 is an oxyalkylene having 2 to 4 carbon atoms; R 2 is an alkyl group having 1 to 15 carbon atoms; and k is an integer from 1 to 9; (b) an alkoxy group (b) having 1 to 15 carbon atoms; (c) an alkoxy alkyl group (c) indicated by the following general formula (2): where R 3 is a straight-chain or branching alkylene group having 1 to 4 carbon atoms; R 4 is a straight-chain or branching alkyl group with 1 to 15 carbon atoms;] (d) an alkyl group (d) having 1 to 15 carbon atoms; and (e) a group (e) indicated by general formula (3): where R 5 is straight-chain or branching alkylene group having 1 to 4 carbon atoms; OR 6 is an oxyalkylene group having 2 to 4 carbon atoms; R 7 is an alkyl group having 1 to 15 carbon atoms; m is an integer from 1 to 9; and thiophene repeating units (E) wherein the hydrogen atoms at position 3 and/or position 4 of the thiophene ring are substituted by the group (s) and a sulfonate group (f).
