According to the present invention, there is provided a coated film capable of exhibiting an excellent adhesion property to a prism resin used in optical applications such as a backlight unit for liquid crystal displays, etc., in particular, a prism resin adaptable for a high brightness of prisms, i.e., a high-refractive index prism resin. The coating film of the present invention comprises a polyester film and a coating layer formed on at least one surface of the polyester film, which is used for forming a surface functional layer on a surface of the coating layer by using an active energy ray-curable coating material, wherein the coating layer is prepared from a coating solution comprising a compound having a carbon-carbon double bond that is reactive with a carbon-carbon double bond in a compound forming the surface functional layer, and an active methylene-blocked isocyanate compound. |
