ABSTRACT:
An improvement in a method of coating a glass plate surface with a heat-reflecting titanium oxide film, which may optionally comprise other metal oxide(s), by spraying a solution of a thermally decomposable organic titanium compound in an organic solvent onto a sufficiently heated glass plate. As the improvement, the absolute humidity of the spraying atmosphere is maintained below about 0.008 kg H.sub.2 O/kg dry gas, whereby the resultant oxide film is practically free from tiny, opaque spots which are liable to appear in the product of conventional methods and exhibits improved resistance to chemical attacks.
