Abstract:
A decorative 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 substrate contains a polycarbonate at least in its surface close to the polymer layer. The polymer layer is a cured product of a polymerizable composition. The polymerizable composition contains a release agent, a polyfunctional acrylate containing one or both of an ethylene oxide group and a propylene oxide group, and 2-(2-vinyloxyethoxy)ethyl acrylate. The polymerizable composition contains, in terms of active components, given proportions of the release agent and the 2-(2-vinyloxyethoxy)ethyl acrylate. The polymerizable composition contains, in terms of active components, a given total amount of the ethylene oxide group and the propylene oxide group in the polyfunctional acrylate and the 2-(2-vinyloxyethoxy)ethyl acrylate.
