Aqueous suspension for pyrolytic spray coating, coated article comprising a sprayed pyrolytic transparent film, method of mixing the spray coating and method of coating a glass substrate with the transparent film

The durability of a transparent pyrolytic spray applied coating is improved by providing a spray solution of metal acetylacetonates having different particle size distribution. More particularly, the particle size distribution of each of the metal acetylacetonates is a function of its melting temperature, and optionally of its melting temperature and solubility.
