摘要： The present invention provides a method making it possible to stably prepare a transparent film in which a cured layer having a micro protrusion and recess face structure is formed on the surface of a base material film. The preparation method of the present invention includes a step of sandwiching an active energy beam-curable resin composition including a photopolymerization initiator which can initiate polymerization of a polymerizable compound by absorbing light between the surface of a base material film which is supported by a supporting film, and a mold which has an inverse structure of the micro protrusion and recess face structure on the surface; a step of obtaining the transparent film supported by the supporting film by means of irradiating the active energy beam-curable resin composition with ultraviolet rays from the supporting film side; and a step of separating the transparent film and the mold.

摘要： A method for manufacturing a light transmissive film having a cured resin layer with a fine concavo-convex structure on a surface of a base material film is provided. The method includes sandwiching an active energy ray-curable composition including a mold dissolving component between a mold having an inversion structure of the fine concavo-convex structure and the base material film, obtaining a light transmissive film in which a cured resin layer having the inversion structure of the mold transferred is formed on one surface of the base material film, and separating the obtained light transmissive film and the mold. Thus, it is possible to productively manufacture a light transmissive film, and to prevent the deposition of an attachment on the mold surface and the contamination of the mold surface. Moreover, a light transmissive film can be manufactured having excellent performances, such as antireflection properties.
