Title:
PROCESS FOR PRODUCING FILM
Document Type and Number:
WIPO Patent Application WO/2010/100902
Kind Code:
A1
Abstract:
A process for stably producing a transparent film which comprises a base film and, formed on a surface thereof, a cured layer having a finely roughened structure. The process comprises: a step in which an actinic-energy-ray-curable resin composition (21) containing a polymerization initiator that can absorb light having a wavelength of 340 nm or longer to initiate polymerization of a polymerizable compound is sandwiched between a surface of a base film (18) supported on a substrate film (17) that has light transmittances of 10% or lower in the wavelength range of 190-310 nm and of 60% or higher in the wavelength range of 340-900 nm and a mold (22) having, on the surface, the reverse of the finely roughened structure; a step in which the actinic-energy-ray-curable resin composition (21) is irradiated with ultraviolet from the substrate film (17) side to obtain a transparent film (16) supported on the substrate film (17); and a step in which the transparent film (16) is separated from the mold (22).
