HEAT-SCREENING GLASS

摘要

The present invention provides a heat-screening glass provided with a protective film having improved wear resistance and chemical resistance in comparison with a protective film of silicon dioxide. A heat-screening glass according to the present invention is composed of a transparent sheet glass and a heat-screening film coated thereon and a protective film made of silicon oxynitride as an outermost layer. The protective film is made of silicon oxynitride represented by the formula SiOxNy (where x ranges from 0.65 to 1.25 and y ranges from 0.05 to 0.67).
