The present invention relates to an UV coating special for PET window film and its preparation method. A pigmented UV-curable window-film coating comprising the following components in parts by mass: UV monomer: 3-40, modified acrylate: 10-50, photoinitiator: 1-10, leveling agent: 0.4-2, pigment: 3-20, coupling agent: 0.5-1.5 and dispersant: 0.4-0.8. The pigmented window film according to the present invention has the functions of being difficult to fade, UV resistance and excellent outdoor weather-resistance as well as the functions of surface-scratch resistance. The color or hue of the pigment itself can remain unchanged for several or even a dozen years. Thus, a PET window film produced from a pigment with good weather resistance can guarantee that it will keep its original color for several to a dozen years and its performance will not be influenced by outdoor environmental factors.
