ABSTRACT:
The present invention relates to a method of depositing rutile type titanium dioxide, and a substrate and glass flakes having rutile type titanium dioxide obtained using the method fixed thereto. An object of the present invention is to make heating essentially unnecessary and simplify the manufacturing process, thus reducing costs, and also enable rutile type titanium dioxide to be fixed easily even to a substrate having low heat resistance. This object is attained by depositing rutile type crystals from a titanium-containing solution through a neutralization reaction under conditions of a temperature in a range of 55 to 85° C. and a pH of not more than 1.3.
