<p>To provide a process for producing a glass substrate provided with an aluminum oxide-containing silicon oxide film having a low refractive index and a high light transmittance, with good production efficiency, with which an aluminum oxide-containing silicon oxide film excellent in the moisture resistance can be directly formed on a glass substrate or a glass ribbon at high temperature. (1) A process for producing a glass substrate provided with an aluminum oxide-containing silicon oxide film, which comprises applying a coating liquid containing an organopolysiloxane and an organic aluminum complex to a glass substrate within a temperature range of from 400 to 650°C to form an aluminum oxide-containing silicon oxide film on the glass substrate, and (2) a process for producing a glass substrate comprising forming molten glass into a glass ribbon, annealing the glass ribbon and cutting it to produce a glass substrate, wherein a coating liquid containing an organopolysiloxane and an organic aluminum complex is applied to the glass ribbon at a position where the glass ribbon is within a temperature range of from 400 to 650°C to form an aluminum oxide-containing silicon oxide film on the glass ribbon.</p> |
