<p>PROBLEM TO BE SOLVED: To provide a double-side coated film which can minimize increase in a film haze even after subjected to processes under severe conditions such as a prolonged heat treatment under the condition of 180°C, a sputtering process under the condition of a high tension, and a durability test in a high temperature and high humidity environment, and which exhibits excellent optical characteristics and visibility even after the film is processed into a product for an optical member.SOLUTION: The double-side coated film comprises: a polyester film having a thickness of 10 to 80μm and having a layered structure of at least three layers, in which a polyester layer having a thickness of 4μm or more, as the outermost surface layers, has a softening point higher than a softening point of other layers; a coating layer on one surface of the polyester film; and an active energy ray-curable resin layer containing a binder polymer having an acrylate structure on the opposite surface. The double-side coated film exhibits at most 0.4% change rate (ΔH) of a film haze before and after a heat treatment (at 180°C for 90 minutes).</p> |
