Method for producing antifouling film

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 comprising:

• 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 containing an antifouling agent that contains a compound containing a perfluoro(poly)ether group,
• the first release agent containing a compound that contains a perfluoro(poly)ether group, a hydrolyzable group, and a Si atom,
• the second release agent containing a compound represented by the following formula (F):
• R111—(R112O)m—R113 (F)
• wherein R111 and R113 are each individually a fluorine atom or a —OH group;
• R112 is a C1-C4 fluorinated alkylene group;
• and m is an integer of 2 or greater.
