CONDUCTIVE POLYMER MICROPARTICLE, CONDUCTIVE POLYMER MICROPARTICLE DISPERSION AND PRODUCTION METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a conductive polymer microparticle having both excellent conductivity and dispersibility; and to provide a conductive polymer microparticle dispersion using such conductive polymer microparticles, excellent in dispersion uniformity and dispersion stability, and formable of a uniform coating film with high conductivity and high transparency.

SOLUTION: The conductive polymer microparticle is obtained by doping a dopant component to a π-conjugated conductive polymer, wherein the dopant component at least includes (a) a polyester resin-based compound having a sulfonic acid group and (b) a low molecular aromatic sulfonic acid compound.
