Abstract

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.
