Abstract:
Provided is an ultraviolet-radiation absorbing glass product, characterized by: having a transmittance of ultraviolet radiation (TUV), as specified by ISO 9050: 2003, of 2% or less at a plate thickness of 3.5 mm, and transmittance of visible light (TVA) of 8 to 28% inclusive, based on the Standard Illuminant A at a plate thickness of 3.5 mm; and the color of the glass, as denoted by the chromaticity coordinates x, y in the XYZ color coordinate system based on a 2-degree visual field of the Standard Illuminant C as specified by JIS Z8701: 1999, satisfying the following expressions (1) and (2). (1) y≥−0.735×x+0.544 (2) y≥1.389×x−0.089
