Abstract: The present invention provides a film application method that can prevent entry of foreign substances and air bubbles between the film and the application target even when the film is applied in a general environment in which foreign substances such as dust are floating. The film application method is a film application method that applies a functional film to a substrate, the method including the steps of: (1) applying a first adhesive layer to the substrate, with a foreign-substance-removing unit including the first adhesive layer and a first film being overlaid onto a main unit including a second film, a second adhesive layer, and the functional film; and (2) while peeling off both the foreign-substance-removing unit and the second film, with one end of the functional film fixed to the substrate, by pulling ends of the foreign-substance-removing unit and the second film adjacent to the fixed end of the functional film through between the substrate and the functional film, applying the second adhesive layer exposed by removal of the second film to the surface of the substrate exposed by removal of the foreign-substance-removing unit.

Abstract: The present invention provides an optical member with which degradation of adhesion between a substrate containing triacetylcellulose and a polymer layer caused by moisture absorption is suppressed. An optical member according to the present invention includes a substrate and a polymer layer in direct contact with the substrate and having an indented structure on a surface thereof, the indented structure including multiple protrusions formed at a pitch not greater than a wavelength of visible light. Triacetylcellulose is present in at least a surface of the substrate on the polymer layer side, the polymer layer is formed from a polymerizable composition polymerizable by active energy ray irradiation, and the polymerizable composition contains 30 parts by weight or more and 75 parts by weight or less of a polyfunctional acrylate, 25 parts by weight or more and 60 parts by weight or less of a monofunctional monomer having a tertiary amide group, and 0.1 parts by weight or more and 10 parts by weight or less of a fluorine-containing compound having a reactive group.
