(57) [Abstract] [Purpose] Transparent and ultraviolet rays are shielded without deteriorating the optical characteristics and the heat ray infrared ray shielding performance, and especially abrasion and scratch resistance and durability are maintained while sufficiently shielding and maintaining around 400 nm. The property is remarkably improved, and it is possible to obtain a window material for automobiles as well as a window material for construction, which can be used for a long period of time as a single plate. [Structure] On the surface of a transparent substrate, a silicone-based primer coating solution prepared by dissolving and adding a fluorescent whitening agent, an ultraviolet absorber and an infrared absorber is applied and cured by heating to form an ultraviolet and infrared absorbing thin film, An ultraviolet and infrared absorption glass coated with a solution of a polysilazane-based mixture to form a coating film. |
