Abstract
A low-reflection coated glass sheet of the present invention includes a glass sheet and a low-reflection coating. The low-reflection coating is formed on at least a portion of one principal surface of the glass sheet, and contains a binder containing silica as a main component, fine silica particles bound by the binder, and fine titania particles bound by the binder. For the low-reflection coated glass sheet, a transmittance gain is 1.7% or more. The low-reflection coating contains 25 mass % to 43 mass % of the silica which is the main component of the binder, 40 mass % to 64 mass % of the fine silica particles, and 10 mass % to 20 mass % of the fine titania particles, based on the total mass of the low-reflection coating. As such, the low-reflection coated glass sheet of the present invention has high abrasion resistance and is capable of exhibiting photocatalytic properties and hydrophilicity when irradiated with light.
