Abstract: A hard coat film for optical applications which suppresses formation of defects on the surface derived from roughness of the surface of the substrate film, exhibits excellent scratch resistance and crack resistance and suppresses curling of the substrate film is provided. The film for optical applications comprises (A) a layer of a cured resin 2 which comprises 70% by weight or more of a cured resin derived from a difunctional urethane acrylate-based oligomer having a weight-average molecular weight of 3,000 or greater and has a thickness of 5 to 25 ?m and (B) a hard coat layer 3 which comprises a resin cured by irradiation with an ionizing radiation and has a thickness of 1 to 15 ?m, layers (A) and (B) being successively laminated on one face of a substrate film 1.
