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 5):
The ultraviolet absorbing glass according to  claim 1 , satisfying A/B being 1.8 or more and A/C being 1.05 or more, wherein:\n the A indicates\n \u22122.73[Fe 2 O 3 ]\u22125.19[FeO]\u22120.85[TiO 2 ]+9.94[NiO]+28.48[Cr 2 O 3 ]+231.19[CoO]\u22124169.28[Se ]+913.24[TiO 2 ][Se]\u22121.71[Fe 2 O 3 ][TiO 2 ]+100.71; \n the B indicates\n 24.88[Fe 2 O 3 ]\u2212130.39[FeO]+21.54[TiO 2 ]\u221293.79[NiO]\u2212782.99[Cr 2 O 3 ]\u22121402.05[CoO]+299 97.75[Se]\u22124613.21[TiO 2 ][Se]\u22125.01[Fe 2 O 3 ][TiO 2 ]+60.53; and \n the C indicates\n 6.07[Fe 2 O 3 ]\u221237.46[FeO]+2.55[TiO 2 ]\u22124.27[NiO]\u2212183.6[Cr 2 O 3 ]\u2212433.37[CoO]+6265.9[Se]\u2212206.26[TiO 2 ][Se]\u22120.65[Fe 2 O 3 ][TiO 2 ]+91.92, \n wherein an expression of a component surrounded by brackets shows a content (mass % based on oxides) of the component contained in the ultraviolet absorbing glass.
