UV-BLOCKING GLASS PLATE, AND GLASS WINDOW FOR VEHICLES USING SAID GLASS PLATE

The invention provides a glass plate which has superior UV transmission-blocking characteristics, has low to moderate-level of visible light transmittance, is relatively thin, substantially blocks transmission of UV from sunlight, and has superior solar radiation-blocking characteristics. The glass plate according to the invention has a thickness of 1-5 mm, a Tuv380 of 1.5% or less, a Tuv400 of 2.5% or less, a visible light transmittance (YA) of 5-40%, and a solar radiation transmittance (TG) of 5-45%, and comprises, in addition to a predetermined matrix composition, a glass composition containing, by mass, 1.0-5.0% of T-Fe2O3, 1.0-5.0% of TiO2, and 50-600 ppm of CoO, as coloring components, wherein the FeO proportion is 5-40%, and the sum of TiO2 and twice of T-Fe2O3 is 7.0% or more. 本发明提供种玻璃板，其紫外线的透射的阻挡特性优异，具备低到中等程度的可见光透射率，较薄，实质上阻止来自太阳光的紫外线的透射，日射屏蔽特性也优异。本发明所涉及的玻璃板的厚度：1～5mm、Tuv380：1.5％以下、Tuv400：2.5％以下、可见光透射率(YA)：5～40％、日射透射率(TG)：5～45％，本发明所涉及的玻璃板包含如下的玻璃组合物：在规定的母组成的基础上，作为着色成分，以质量基准计，包含T－FeO：1.0～5.0％、TiO：1.0～5.0
