GLASS PLATE WITH INFRARED SHIELDING LAYER AND PROCESS FOR PRODUCING THE SAME

摘要

A glass plate with infrared shielding layer that excels in visible light and radiowave transmissions, exhibiting low infrared transmittance, and that is applicable to regions requiring mechanical durability, such as automobile window glass; and a process for producing the same. There is provided a glass plate with infrared shielding layer characterized by having a glass substrate and, superimposed on a surface thereof, an infrared shielding layer composed of contiguously arranged first layer and second layer (first layer arranged on the side of glass substrate) wherein the first layer is a 0.2 to 2 µm thick layer having ITO microparticles of = 100 nm average primary particle diameter bound to each other by means of a metal oxide matrix containing silicon oxide and titanium oxide while the second layer is a 0.02 to 0.3 µm thick metal oxide layer containing silicon oxide and titanium oxide.
