摘要： PROBLEM TO BE SOLVED: To obtain a glare-proof coating material that uses low refractive index/light transmission properties/irregular reflection of secondary particles of cubic hollow particles composed of silica shells produced at a low cost and is used for a use requiring a low cost. SOLUTION: When the glare-proof coating material 1 is applied to the surface of a glass substrate 4, a glare-proof coating film having a structure in which secondary particles 2 having sizes in the range of 0.5μm-5μm are projected from a thin coating film of an acrylic resin 3 is formed. Since the cubic hollow particles 10 composed of silica shells constituting the secondary particles 2 have thin thickness of the silica shells 11 of about 1nm-5nm and large volumes of the hollow parts 12, the whole glare-proof coating film has a low refractive index of 1.2-1.3, and the cubic hollow particles 10 composed of the silica shells have a function in which a visible light L1 made incident approximately vertically to the glare-proof coating film is passed through the silica shells 11 and the hollow part 12, permeated as it is and a visible light L2 slantingly made incident is scattered on the silica shells 11.
