COATING LIQUID FOR FORMING DARK COLOR TRANSPARENT CONDUCTIVE FILM AND DARK COLOR TRANSPARENT CONDUCTIVE FILM FORMED BY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a coating liquid for forming a dark color transparent conductive film for easily manufacturing a film which lowers transmittance without scattering the visible light of a CRT screen, has the better electrical conductivity than heretofore and has an effect in shielding a low-frequency electric field at a low cost by using a coating method and the dark color transparent conductive film formed by using this liquid. ;SOLUTION: This coating liquid for forming the dark color transparent conductive film is prepd. by dispersing ruthenium oxide particulates as conductive particulates into a polar solvent and coating these ruthenium oxide particulates with coating layers of silver in part or the whole of the particle surfaces and the grain size thereof is ≤50nm. The polar solvent in the constitution described above further contains the partial hydrolyzed polymer of alkyl silicate. The dark color transparent conductive film is obtd. by coating a base material with the coating liquid for forming the dark color transparent conductive film and further coating the film described above with a soln. of the partial hydrolyzed polymer of alkyl silicate, then baking the coating.;COPYRIGHT: (C)1998,JPO
