ANTIFOULING FILM

The An antifouling film includes: a substrate; and a polymer layer 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 98 wt % of a polyfunctional acrylate, 0.5 to 10 wt % of a fluorine-based release agent, and 1 to 14 wt % of a monofunctional amide monomer. The polymer layer has a bottom temperature at which a storage modulus E′ of the polymer layer is minimum of 90° C. to 150° C. and a minimum storage modulus E′ of 0.9×108 to 4.5×108 Pa in a dynamic viscoelasticity measurement within a measurement temperature range of −50° C. to 250° C. and at a temperature increasing rate of 5° C./min and a frequency of 10 Hz.
