Title:
METHOD FOR PRODUCING LIGHT-TRANSMITTING FILM, ACTIVE ENERGY RAY-CURABLE COMPOSITION, AND LIGHT-TRANSMITTING FILM
Document Type and Number:
WIPO Patent Application WO/2012/091129
Kind Code:
A1
Abstract:
The present invention relates to a method for producing a light-transmitting film wherein a cured resin layer having a microrelief structure is formed on the surface of a base film, said method comprising: a step in which an active energy ray-curable composition containing a mold dissolving component is held between the base film and a mold that has the inverse structure of the microrelief structure; a step in which a light-transmitting film wherein a cured resin layer, to which the inverse structure of the mold is transferred, is formed on one surface of the base film; and a step in which the thus-obtained light-transmitting film is separated from the mold. According to the present invention, a light-transmitting film can be produced with high productivity and the mold surface can be prevented from being contaminated by materials adhered and accumulated thereon. Consequently, a light-transmitting film that has excellent performances such as excellent antireflection performance can be produced.
