Method of making a coated glass substrate with heat treatable ultraviolet blocking characteristics

A method of making a coated article including a UV blocking coating, the method comprising:

• applying a first wet coating solution comprising a mixture of compounds of titanium, cerium, and silicon on a glass substrate,
• at least partially curing the first wet coating solution to form a UV blocking coating on the glass substrate, the UV blocking coating comprising a mixture of oxides of cerium, titanium, and silicon, the UV blocking coating consisting essentially of:
• titanium oxide:
• from about 20-25% by mole
• cerium oxide:
• from about 20-25% by mole
• silicon oxide:
• from about 30-60% by mole,
• wherein the UV blocking coating has a refractive index (n) of from about 1.66 to 1.96, and wherein the UV blocking coating has a thickness ranging from about 0.75 to 1.2 μm, and wherein the UV transmission of the UV blocking coating is no greater than about 10%;
• applying a second wet coating comprising a photomonomer and/or photopolymer on the glass substrate over the UV blocking coating;
• curing the second wet coating through exposure to radiation, wherein the second wet coating has a thickness of from about 5 to 10 μm;
• and
• thermally tempering the glass substrate with the UV blocking coating thereon, wherein the second coating enables the first coating to remain substantially crack-free during and/or after thermal tempering and/or heat treatment.
