  • Coating solution for forming colored film on glass substrate, glass plate with such colored film, and process for producing such glass plate
    Patent number: 6572918
    Abstract: A first coating solution for forming a colored film on a glass substrate contains a titanium alkoxide; a silicon alkoxide; a coloring agent that is a nitrogen-containing organic compound; and an organic solvent dissolving the titanium alkoxide, the silicon alkoxide and the nitrogen-containing organic compound. A second coating solution therefor contains a titanium alkoxide; a silicon alkoxide; and an organic solvent dissolving the titanium alkoxide and the silicon alkoxide. At least one of these titanium alkoxide and silicon alkoxide of the second coating solution contains in the molecule a nitrogen-containing organic group derived from a nitrogen-containing organic compound.
    Type: Grant
