Process for producing glass substrate provided with inorganic fine particle-containing silicon oxide film

Abstract

To provide a process for producing a glass substrate provided with an inorganic fine particle-containing silicon oxide film, wherein inorganic fine particles having a desired particle size may be used depending on intended optical properties, and the range of selection of the inorganic fine particles is wide. A process for producing a glass substrate provided with an inorganic fine particle-containing silicon oxide film, which comprises applying a coating liquid containing inorganic fine particles 14, a hydrolysate of an alkoxysilane, and one of or both water and a (poly)ethylene glycol, to a glass substrate 10 to form an inorganic fine particle-containing silicon oxide film 12; or which comprises forming molten glass into a glass ribbon, annealing the glass ribbon, and at the time of cutting the glass ribbon to obtain a glass substrate, applying a coating liquid containing inorganic fine particles, a hydrolysate of an alkoxysilane, and one of or both water and a (poly)ethylene glycol, to the glass ribbon to form an inorganic fine particle-containing silicon oxide film.
