摘要:
The present invention provides a method for producing an antifouling film having excellent antifouling properties and rubbing resistance. 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 pushing the substrate to a die with the resin in between to form the uneven structure on a surface of the resin; and Process (3) 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 compound containing a perfluoro(poly)ether group. The die includes a surface having undergone release treatment using a release agent containing a compound that contains a perfluoro(poly)ether group, a hydrolyzable group, and a Si atom.
