Abstract:
A method for manufacturing soil-resistant glass the surface of which is covered with a coating film having a high hardness, and the soil-resistant glass are provided. A coating film comprising titania or/and titania-silica is formed by coating a glass surface with a photocatalyst solution comprising the titania or/and the titania-silica each having a photocatalytic function and heating the applied photocatalyst solution at a temperature higher than at least 100° C. The heating temperature may be a temperature higher than 100° C. and 300° C. or lower. The time of heating at the above-mentioned temperature may be at least 2 minutes or longer.
