METHOD FOR MANUFACTURING COLOR COATED PLATE GLASS

摘要

The present invention provides a method of producing a colored film-attached glass sheet having good hardness and good coloration and capable of favorably maintaining the good coloration for a long time. The method of producing a colored film-attached glass sheet including a glass sheet and a colored film formed on at least one surface of the glass sheet includes: a step of obtaining a colored film-forming coating solution by mixing the following components: (a) a reaction product obtained by reacting an amino group-containing silane compound with at least one boron compound selected from the group consisting of H₃BO₃ and B₂O₃; (b) a metal alkoxide and/or a metal alkoxide condensate; (c) a synthetic resin; (d) a triazine-based UV absorber; (e) a solvent substantially consisting of a non-aqueous solvent having an SP value of 8 to 11.5 (cal/cm³)^1/2; and (f) a pigment, wherein the colored film-forming coating solution contains the UV absorber in an amount of 5 to 12% by mass relative to the total solids content and the pigment in an amount equal to 0.02 to 0.50 times the amount of the UV absorber by mass ratio.
