Patent ID: 8728351

Claim:
A conductive polymer solution, comprising: a π-conjugated conductive polymer, a polyanion, a compound having an oxetane ring, and a solvent; wherein, the π-conjugated conductive polymer is poly(3,4-ethylenedioxythiophene), the compound having an oxetane ring is one selected from xylenebisoxetane, 3-ethyl-3{[3-ethyloxetane-3-yl)methoxy]methyl}oxetane, and 4,4′-(3-ethyloxetane-3-ylmethyloxymethyl)biphenyl, and the amount of the compound having an oxetane ring is within the range of 1 to 500% by mass based on a value of 100% by mass for the total amount of the p-conjugated conductive polymer and the polyanion.
