Abstract
A method for producing an optical film is provided and includes: simultaneously coating at least two coating solutions over a transparent support, the at least two coating solutions each containing a solvent and a solute; and drying the solvent in each of the at least two coating solutions to provide at least two coating layers. When the at least two coating layers are, . . . n−1 and n layers in sequence from the outermost surface of the at least two coating layers toward the transparent support, n being an integer of 2 or more, the main component of the solute in the n-th layer is insoluble or sparingly soluble in the main component of the solvent in the (n−1)-th layer.
