PURPOSE: To obtain infrared-shielding glass whose chemical stability and scuffing resistance are markedly improved by using tantalum oxide as the outermost dielectric layer from the glass base plate.
CONSTITUTION: The subject infrared shielding glass is constituted by forming, in turn on the glass base plate 1, the first layer of clear dielectric film 2, the second layer of nitride film 3, and the third layer of tantalum oxide film 4. The base glass is a infrared shielding glass such as soda lime glass. The film 2 is titanium oxide, and the film 3 is titanium nitride or zirconium nitride. The use of the clear dielectric film 4 of tantalum oxide enables production of the infrared shielding glass having excellent properties prescribed above. Thus, the product can be applied to the more drastic fields, for example, as an infrared shielding car panes.
