ULTRAVIOLET AND INFRARED RAY SHIELD GLASS

PROBLEM TO BE SOLVED: To provide a heat ray reflection glass partially improved in transmissivity by reforming a coating film. SOLUTION: A 1st layer having the refractive index of 1.8-2.0, a 2nd layer having the refractive index of >=2.1 and a 3rd layer having the refractive index of 1.6-2.0 are...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a heat ray reflection glass partially improved in transmissivity by reforming a coating film. SOLUTION: A 1st layer having the refractive index of 1.8-2.0, a 2nd layer having the refractive index of >=2.1 and a 3rd layer having the refractive index of 1.6-2.0 are formed in this order on the surface of a glass, an ultraviolet absorbing oxide is incorporated in each layer, the film thickness of each layer is controlled to 10-100nm, the ultraviolet transmissivity in 370nm wavelength is controlled to =70%, the solar radiation transmissivity is lower than that of the plate glass by >=5% and (x) and (y) in xyz color specification system are controlled to
