PURPOSE:To obtain a heat-resistant inorg. paint which gives a coating film having excellent gloss, strength, water resistance, etc., by partially hydrolyzing a composite alkoxide composed of a Si alkoxide and an alkoxide of Ti, Al and/or Zr to form a sol. CONSTITUTION:A composite alkoxide composed of an Si alkoxide (A) and at least one member (B) selected from the group consisting of a Ti alkoxide, an Al alkoxide and a Zr alkoxide, is prepd. 7-25pts.wt. component B is used per 100pts.wt. component A. The composite alkoxide is partially hydrolyzed to form a sol, thus obtaining the desired heat-resistant inorg. paint. The partial hydrolysis of the composite alkoxide is carried out by reacting less than 1, pref. 0.08-0.6mol of water with 1mol of the OR group of the alkoxide.
