Abstract
This article is a glass substrate having a coating thereon. The coating strongly absorbs certain ultraviolet radiation. The preferred coating absorbs ultraviolet radiation at wavelengths ranging from 230 up to at least 280 nm while providing high transmission throughout a region of visible wavelengths. The preferred coating consisting essentially of three layers, wherein the first layer adjacent the substrate is a mixture of SiO.sub.2 and TiO.sub.2 ; the second layer is TiO.sub.2 and the third layer farthest from the substrate is SiO.sub.2.
