Abstract:
The purpose of the present invention is to provide an ultraviolet-absorbent glass that is suitable as a dark gray glass, that has a very low ultraviolet transmittance (TUV), and that has excellent color rendering properties for green. The present invention relates to an ultraviolet-absorbent glass in which: the ultraviolet transmittance (TUV) as defined in ISO 9050:2003 is 2% or less for a thickness of 2.8 mm; the visible light transmittance (TVA) based on a standard A light source is 10% to 30% inclusive for a thickness of 2.8 mm; the energy transmittance (TE) as defined in JIS R 3106:1998 is 30% or less for a thickness of 2.8 mm; a ratio R14/R9 for color rendering indices as defined in ISO 9050:1990 and JIS Z 8726:1990 is 1.8 or greater; and a ratio R14/R1 is 1.05 or greater.

Claim (Index 7):
The ultraviolet absorbing glass according to  claim 1 , wherein the total iron content in terms of Fe 2 O 3  is 2.0% or more in mass % based on oxides.
