The light-shielding layer is disposed on the first side of the tempered glass substrate, two opposite sides of the light-shielding layer are a first side and a second side, and the second side of the light-shielding layer is closer to the tempered glass substrate than the first side of the light-shielding layer. The reflective layer is disposed at the first side of the light-shielding layer.

A method for preparing an article, the structure of which comprises a substrate of a glass or a glass-ceramic and a coating fixed to at least one portion of the surface of the substrate. In a characteristic way, the coating is generated from at least one loaded polysilsesquioxane resin; the at least one polysilsesquioxane resin not containing any aryl radical in its structure.

Coating liquid used for forming an ultraviolet absorption coating on a surface of an object such as glass and the like, ultraviolet absorption glass arranged with the ultraviolet absorption coating formed by the coating liquid, and a method for preparing the ultraviolet absorption glass. The coating liquid used for forming the ultraviolet absorption coating, the ultraviolet absorption glass and the method for forming the ultraviolet absorption glass, by storing and releasing electrons excited by ultraviolet lights in an ultraviolet absorber, reduce the excited electrons that are gradually accumulated during a process in which the ultraviolet absorber absorbs the ultraviolet lights, thus protecting the ultraviolet absorber and a silicon dioxide matrix, preventing the ultraviolet absorption glass from discoloring or devitrifying, ensuring weather resistance of the ultraviolet absorption coating and ensuring color consistency of the ultraviolet absorption glass.

A construction board includes a foam body having first and second planar surfaces, said foam body including a polyisocyanurate foam matrix defining a plurality of closed cells, said closed cells being at least substantially devoid of hydrocarbon blowing agents, and said foam body being characterized by a density, pursuant to ASTM C303, of at least 2.5 lbs/ft.sup.3; and a facer disposed on a planar surface of said foam body, said facer including a glass substrate having an internal planar surface proximate to said foam body and an external planar surface opposite said foam body, a first coating disposed on said external surface, and a second coating disposed on or proximate to said internal surface, where said first coating disposed on said external surface includes an inert filler, and where said second coating disposed on or proximate to said internal surface includes intumescent material.
