ABSTRACT:
To produce a heat-reflecting glass plate by coating a glass plate surface with a titanium oxide film, a solution of a thermally decomposable organic titanium compound is sprayed onto the glass plate surface while the glass plate is kept heated. As the improvement, use is made of a chelate compound of titanium formed by coordination of two molecules of either acetylacetone or ethyl acetoacetate as chelate ligands and two molecules of a polyalcohol as nonchelate ligands to a titanium atom. Preferably the polyalcohol is a 1,3-diol, and particularly 2-ethyl-1,3-hexane diol. This chelate compound is not easily influenced by moisture and gives a titanium oxide coating film of superior quality.
