PREPARATION OF INK FOR FORMING TRANSPARENT CONDUCTIVE FILM

摘要

PROBLEM TO BE SOLVED: To provide a preparation method of an ink for forming a transparent conductive film which ink can be used for forming a dense and uniform transparent conductive film and is excellent in continuous printability. SOLUTION: A solution for forming a transparent conductive film comprises at least one kind of partially hydrolyzed organic metal compound, an alcohol having a boiling point of 30-below 150 deg.C, at least one kind of low boiling-point solvent selected from alcoholes, ketones, esters and ethers, at least one kind of stabilizer selected from amines, organic acids, inorganic acids,β-diketones andβ-ketoesters. This solution is concentrated at normal temperature to 60 deg.C to form a viscous solution. Then at least one kind of high boiling-point solvent selected from glycols, carbitols and cellosolves having a boiling point of 150-280 deg.C is added into the viscous solution to control the ink such that the high boiling-point solvent be to occupy 40-95 wt.% of the solvents and the ink viscosity be 5-200 mPa.s.
