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.
