COATING COMPOSITION FOR CONDUCTIVE POLYMERIC TRANSPARENT THIN FILM HAVING HIGH REFRACTION RATIO

摘要

PURPOSE: A coating composition is provided that can be prepared by using a dispersion solvent and a high refractive inorganic sol which is a metal oxide dispersible in a conductive polymer solution with a high ratio and has a refraction ratio of RI = 1.60. CONSTITUTION: A coating composition for a conductive polymeric transparent thin film having a high refraction ratio comprises 2 to 20 wt% of an aqueous conductive polymer solution with a solid content of 1.2 to 1.5 wt%, 0.5 to 20 wt% of high refractive inorganic sol with a solid content of 14 to 16 wt%, 50 to 97.4 wt% of alcohol solvent having a carbon atom of 1 to 3 below, 0.1 to 10 wt% of amide solvent, 0.005 to 0.05 wt% of water-soluble or alcohol-soluble resin binder, and 0.005 to 0.05 wt% of sulfonic acid monomer dopant.
