More Information
Summary:According to the present invention, there is provide a coated film which can be suitably used in various applications in which it is required to provide an ultraviolet ray-curable resin layer having a high brightness, for example, as a member for a backlight unit for liquid crystal displays. The present invention relates to a coated film comprising a polyester film, a coating layer formed on at least one surface of the polyester film, and an ultraviolet ray-curable resin layer having a refractive index of not less than 1.57 which is formed on a surface of the coating layer, in which the coating layer is prepared from a coating solution comprising a polyurethane resin comprising a carbon-carbon double bond capable of reacting with a carbon-carbon double bond in a compound forming the ultraviolet ray-curable resin layer.
