Abstract
PURPOSE: To form an anti-clouding coated layer on cover glass for a wrist watch by coating the glass with one or ≥2 kinds of metallic compounds selected from oxide, fluoride, boride, nitride, silicide, carbide and sulfide or further carrying out annealing.
CONSTITUTION: The back side of cover glass for a wrist watch is coated with one or ≥2 kinds of metallic compounds selected form oxide, fluoride, boride, nitride, silicide, carbide and sulfide in combination by sputtering, ion plating or other method, or the coated layer is further heated and annealed to form a film with superior anti-clouding properties.
