ABSTRACT:
The present invention provides a low reflection glass plate which has an effect of reducing reflectance against light even at an incident angle of 60° sufficiently, in high yield. A process for producing a low reflection glass plate, characterized by the use of a treating fluid (1) comprising a resin B1, fine gold particles, an organic metal compound of at least one metal (M1) selected from the group consisting of iron, titanium and zirconium, and an organic solvent, and a treating fluid (2) comprising a film-forming compound, a resin B2 having the same thermal decomposition temperature as the resin B1 or a higher thermal decomposition temperature than the resin B1, wherein said process comprises applying the treating fluid (1) on the surface of a transparent glass substrate, followed by drying at a temperature of from 50 to 250° C. to remove the organic solvent, further applying the treating fluid (2), followed by drying at from 50 to 250° C. to remove the organic solvent, and then baking the treated transparent glass substrate at a temperature of from 400 to 800° C.
