Abstract:
1. A method for manufacturing soil-resistant glass a surface of which is covered with a coating film comprising titania-silica having a photocatalytic function, the method comprising coating a glass surface with a photocatalyst solution comprising the titania-silica without using an undercoat or mixing another solution, and heating to dry the glass surface coated with the photocatalyst solution to form the coating film, wherein the photocatalyst solution comprising the titania-silica is a sol of titania-silica in which titania and silica have been bonded via a peroxy bond, produced by further adding hydrogen peroxide to peroxidize amorphous titania to which tetraethyl orthosilicate has been added, and the coating film is formed with a heating temperature from 110° C. to 160° C., and the formed coating film has a film hardness of 6H or higher as measured according to the Pencil method.
