PROBLEM TO BE SOLVED: To obtain a reflection preventing film comprising a support composed of a cellulose acylate film manufactured by casting a dope using a solvent containing no halogenated hydrocarbon such as methylene dichloride or composed of a cellulose acylate film manufactured by co-casting dopes with fast film forming speed. SOLUTION: The reflection preventing film comprises a cellulose acylate support obtained by casting a solution composed of cellulose acylate dissolved in at least a solvent, selected from a group consisting of a 2-12C ether, a 3-12C ketone and a 2-12C ester, practically containing no halogenated hydrocarbon type solvent or a cellulose acylate support obtained by co-casting a plurality of cellulose acylate solutions and a low refractive index layer of which the refractive index is lower than that of the support. |
