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 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 an 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 a 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.

Method for producing antifouling film

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 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 an 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 a 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.

The invention provides a method for producing a transfer target which is less likely to separate from a substrate or adhere to a mold even when transfer is repeated. The production method includes the steps of: (1) applying a composition containing a fluoropolyether to a release layer of a mold having an uneven pattern on a surface thereof; (2) pressing the mold to a transfer target and transferring the uneven pattern; and (3) releasing the mold from the transfer target, thereby providing the transfer target having a transferred pattern.
