Provided is a coating film which can be suitably used for various uses in which an ultraviolet ray-curable resin layer exhibiting high luminance is needed, examples of such uses including a member for a backlight unit of a liquid crystal display. A coating film having a coating layer formed on at least one surface of a polyester film, and an ultraviolet ray-curable resin layer formed on the surface of the coating layer and having a refraction index of 1.57 or more, wherein the coating layer is formed from a coating liquid containing a polyurethane resin having a carbon-carbon double bond that reacts with the carbon-carbon double bond contained in the compound forming the ultraviolet ray-curable resin layer. |
