    Abstract: The method for producing an optical member of the present invention includes: Process (1) of applying a first resin to a substrate; Process (2) of applying a second resin to at least one of the first resin and a die; Process (3) of pushing the substrate to the die with the first resin and the second resin in between to form a resin layer including on a surface thereof an uneven structure; and Process (4) of curing the resin layer to provide a polymer layer. The die includes a surface after release treatment with a fluorine release agent. The first resin contains a resin component, and the resin component contains predetermined amounts of a (meth)acrylamide compound and a urethane prepolymer containing six or more functional groups. The second resin contains predetermined amounts of a reactive group-containing monomer, a fluorosurfactant, and a fluorine-containing monomer.

    Abstract: An antifouling film includes: a substrate; and a polymer layer disposed on a surface of the substrate and including on a surface thereof an uneven structure provided with projections at a pitch not longer than a wavelength of visible light. The polymer layer is a cured product of a polymerizable composition. The polymerizable composition contains, in terms of active components, 75 to 95 wt % of a polymerizable monomer, 2.5 to 12.5 wt % of a urethane acrylate containing fluorine and an ester, and 2.5 to 9 wt % of a perfluoroalkyl-based monomer containing one (meth)acryloyl group for each molecule. The polymerizable monomer contains a bifunctional acrylate that contains an ethylene oxide group and a multifunctional acrylate that contains no ethylene oxide group. The perfluoroalkyl-based monomer has a fluorine atom concentration of 50 to 60 wt %. The polymerizable composition has an ethylene oxide group concentration of 20 to 50 wt %.
