  • Coating material for forming transparent and conductive film
    Patent number: 6921788
    Abstract: The present invention relates to a paint for forming a transparent conductive thin film characterized in comprising at least a conductive oxide powder comprising a primary granular diameter of no greater than 100 nm; an easily dispersible low-boiling point solvent of the aforementioned conductive oxide powder; a difficultly dispersible high-boiling point solvent of the aforementioned conductive oxide powder; and a binder. By using the paint for forming a transparent conductive thin film, it is possible to form a transparent conductive thin film having superior transparency and conductive properties onto the surface of a transparent material.
