Title:
OPTICAL MEMBER AND POLYMERIZABLE COMPOSITION FOR NANOIMPRINTING
Document Type and Number:
WIPO Patent Application WO/2017/022701
Kind Code:
A1
Abstract:
The present invention provides an optical member in which a decrease in adhesion between a polymer layer and a substrate including triacetylcellulose due to moisture absorption is suppressed. This optical member is provided with a substrate and a polymer layer in direct contact with the substrate, the polymer layer having on a surface thereof an uneven structure in which a plurality of projections are provided at a pitch equal to or less than the wavelength of visible light, and triacetylcellulose is present on at least the surface of the substrate on the polymer layer side thereof, the polymer layer is formed from a polymerizable composition polymerized by irradiation with active energy rays, and the polymerizable composition contains 30 to 75 parts by weight of a polyfunctional acrylate, 25 to 60 parts by weight of a monofunctional monomer having a tertiary amide group, and 0.1 to 10 parts by weight of a fluorine-containing compound having a reactive group.
