Abstract:
A method is disclosed for efficiently producing a nanoimprint film with high-accurately formed nanostructures even if a base on which the nanoimprint film is formed is capable of absorbing UV light. The production method of at least one embodiment of the present invention is a production method of a nanoimprint film formed on a base, the nanoimprint film having a surface with nanosized protrusions and recesses formed thereon. In at least one embodiment, the production method includes a first step of applying a UV-curable resin on a base containing a UV-absorbing component to form a film; a second step of irradiating the film with UV light from a top-side surface of the film to form a semi-cured film; a third step of imprinting nanosized protrusions and recesses on the semi-cured film to form a film having a surface with protrusions and recesses formed thereon; and a fourth step of curing the film with protrusions and recesses to form a nanoimprint film.
