Title:
METHOD FOR MANUFACTURING LAYERED FILM, AND METHOD FOR MANUFACTURING LAYERED MEMBER
Document Type and Number:
WIPO Patent Application WO/2021/020302
Kind Code:
A1
Abstract:
Provided is a method for manufacturing a layered film that can be molded into complex shapes. The method for manufacturing a layered film includes: a step for applying, to one surface of a first support substrate having a thickness of 50-600 μm inclusive, a composition for forming an active-energy-ray-curable hard coating layer, and subsequently drying the composition to form an uncured hard coating layer; a step for applying, to one surface of a second support substrate, a composition for forming an active-energy-ray-curable optical interference layer so that the thickness of a resultant uncured optical interference layer is 15-200 nm inclusive, and subsequently drying the composition to form the uncured optical interference layer; and a laminating step for affixing together the surface of the uncured hard coating layer on the side opposite from the first support substrate and the surface of the uncured optical interference layer on the side opposite from the second support substrate to obtain a layered film. The rate of elongation at 160°C of the layered film is 50% or greater.
