    摘要： The present invention provides a method for producing an antifouling film capable of long-term continuous production of an antifouling film having excellent antifouling properties. The method for producing an antifouling film of the present invention is a method for producing an antifouling film including a polymer layer that includes on a surface thereof an uneven structure provided with multiple projections at a pitch not longer than a wavelength of visible light. The method includes Process (1) of applying a resin to a surface of a substrate; Process (2) of applying a second release agent to a surface of a die coated with a first release agent; Process (3) of pushing the substrate to the surface of the die coated with the second release agent with the resin in between to form the uneven structure on a surface of the resin; and Process (4) of curing the resin including the uneven structure on the surface thereof to form the polymer layer. The resin contains an antifouling agent that contains a predetermined compound. The first release agent contains a predetermined compound. The second release agent contains a predetermined compound.

    摘要： The present invention provides a method for producing an optical film excellent in anti-fouling properties and scratch resistance as well as anti-reflection properties. The method includes the steps of: (1) applying a lower layer resin and an upper layer resin; (2) forming a resin layer having the uneven structure on a surface thereof by pressing a mold against the lower layer resin and the upper layer resin from the upper layer resin side in the state where the applied lower layer resin and upper layer resin are stacked; and (3) curing the resin layer, the lower layer resin containing at least one kind of first monomer that contains no fluorine atoms, the upper layer resin containing a fluorine-containing monomer and at least one kind of second monomer that contains no fluorine atoms, at least one of the first monomer and the second monomer containing a compatible monomer that is compatible with the fluorine-containing monomer and being dissolved in the lower layer resin and the upper layer resin.
