Abstract
Colored film-covered glass articles include a glass substrate and a colored film covering the glass substrate, the colored film containing, by wt %, greater than 50 to 95 of silicon oxide, 0.about.30 of at least one member selected from the group consisting of zirconium oxide, tantalum oxide and titanium oxide, 0.about.25 of cerium oxide, 5.about.20 of gold as coloring fine particles as main components. The glass articles have a visible light reflectance at a side of the glass substrate not covered with the colored film is 10.0% or below. The small visible light reflectance is caused by the surface plasmon absorption of the fine particles of gold.
