Patent ID: 8287946

Claim:
A coating process for forming a coating film onto a surface of a glass substrate, comprising coating on the glass substrate a coating fluid comprised of at least one of an ultraviolet-screening agent having a particle diameter of 1-100 nm and an infrared-screening agent, a binder component and 50-95% by weight of a polyhydric alcohol solvent selected from the group consisting of ethylene glycol, propylene glycol, trimethylene glycol, 1,4-butanediol, 1,5-pentanediol, 1,6-hexanediol, and 1,7-heptanediol with a coater having a fluid ejection nozzle with a tip bore diameter of 1.0-2.0 mm at an ejection pressure of 0.01-0.05 MPa; and drying the coated glass substrate solely by heated air to form a coating film having a visible light transmittance of 85% or more.
