Abstract

PURPOSE: To provide antibrittleness, superior heat resistance and superior thermal impact resistance and enhance the chemical resistance, especially the alkali resistance of the mirror surface of a base material by covering the surface with a siliceous transparent protective film of a special composition.
CONSTITUTION: A base material such as aluminum, iron, glass or the like is used properly according to the application of the resulting reflector, and a mirror surface formed on the material is covered with a siliceous transparent protective film consisting of 77.0W99.0mol% SiO2 and 1W23mol% at least one oxide selected from P2O5, B2O3 and Al2O3 other than water by sputtering or other method. Since the protective film contains such oxide as well as silica, it has antibrittleness, superior heat resistance and superior thermal impact resistance, and the chemical resistance, especially the alkali resistance of the mirror surface can be enhanced.
