Abstract: A method for producing an optical film including: laminating a hard coat layer on one side of an optical substrate in roll form, the hard coat layer having a transparent support and an optical anisotropic layer. The transparent support is laminated on the optical anisotropic layer, the one side is a transparent support-side of the optical substrate, the hard coat layer is obtained by coating, drying and curing a composition for forming a hard coat layer containing a curable monomer, a photo-polymerization initiator, and a solvent. The solvent is a mixture of at least one solvent selected from (S-1) and (S-2) and at least one solvent selected from (S-3), or a mixture of at least one solvent selected from (S-1) and at least one solvent selected from (S-2): (S-1) solvents dissolving the transparent support; (S-2) solvents swelling the transparent support; and (S-3) solvents neither dissolving nor swelling the transparent support.
