WIPO Patent Application WO/2018/155317
Kind Code:
A1
Abstract:
The present invention provides an antifouling film which is suppressed in whitening in high temperature/high humidity environments, while having excellent rubbing resistance. An antifouling film according to the present invention is provided with a polymer layer that has a recessed and projected structure in the surface wherein a plurality of projections are provided at a pitch equal to or less than the wavelength of visible light. The polymer layer is a cured product of a polymerizable composition; and if the total amount of the polymerizable composition is taken as 100% by weight, the polymerizable composition contains 50-70% by weight of a polyfunctional acrylate having an ethylene oxide group, 15-30% by weight of a monofunctional acrylate having an amide group, 0.01-5% by weight of a first mold release agent having a perfluoropolyether group and 0.45-5% by weight of a monofunctional second mold release agent having a perfluoroalkyl group and 4 or more CF2 groups in each molecule.
