Ultraviolet protective coating and ultrathin glass coated with same

The invention provides an ultraviolet protective coating, which is prepared from the following raw materials in percentage by mass: 60 to 70 weight percent of glass-based glaze and 30 to 40 weight percent of TiO2, the total mass of the glass-based glaze and the TiO2 is taken as a reference, the addition amount of eucryptite is 0 to 1.5 weight percent, the total mass of a mixture consisting of the glass-based glaze, the TiO2 and the eucryptite is taken as a reference, the addition amount of printing ink is 22 to 25 weight percent, and the addition amount of the printing ink is 0 to 1.5 weight percent. The adding amount of the foaming agent is 0-1wt%. In addition, the invention also provides ultra-thin glass coated with the coating, and a method for coating the coating on the ultra-thin glass. The coating provided by the invention has low transmittance and high reflectivity, and the ultraviolet-visible-infrared light barrier property of the coating is improved. And the warping degree of the coating is obviously
