Ultraviolet-cutoff glass and heat-cutoff glass

摘要

A sheet of ultraviolet- or heat-cutoff glass includes a primer layer, an ultraviolet- or heat-cutoff layer, and a water-repellent layer which are successively deposited on a glass sheet. The water-repellent layer is formed of a vitreous water repellent. Since the water-repellent layer doubles as an overcoat layer, it makes it unnecessary to form a overcoat layer in a separate overcoating process.
