Abstract
Disclosed is a polymer composition for coatings with high refractivity, conductivity and transparency. The composition comprises 2-20 weight % of an aqueous polythiophene-based conductive polymer solution having a solid content of 1.2-1.5 weight %; 0.5-20 weight % of a highly refractive, inorganic sol solution having a solid content of 14-16 weight %; 50-97.4 weight % of an alcohol containing 1-3 carbon atoms; 0.1-10 weight % of an amide solvent; 0.005-0.1 weight % of a water- or an alcohol-soluble resin binder; and 0.005-0.05 weight % of a sulfonic acid group-containing monomer dopant. The composition can be applied to CRT external glass and other transparent substrates to allow thin films which have a refractive index of 1.6-2.0, a transmittance of 90-98% and a surface resistance of 1×10,-1×10,&OHgr;/□.
