METHOD FOR MANUFACTURING OPTICAL MEMBER

Document Type and Number:

WIPO Patent Application WO/2018/012339

Kind Code:

A1

Abstract:

The present invention provides a method for manufacturing an optical member, whereby antifouling properties and abrasion resistance are increased without compromising transparency. This method for manufacturing an optical member is a method for manufacturing an optical member provided with a substrate and a polymer layer having an uneven structure on a surface thereof in which a plurality of projections are provided at a pitch equal to or less than the wavelength of visible light, wherein the method includes a process (1) for dissolving a photocurable resin and a release agent in a solvent and preparing a resin solution, a process (2) for applying the resin solution to the surface of the substrate, a process (3) for performing a heat treatment for removing the solvent from the applied resin solution and forming a resin layer, a process (4) for pressing the substrate against a die in a state in which the resin layer is sandwiched between the die and the substrate and forming the uneven structure on the surface of the resin layer, and a process (5) for curing the resin layer by photoirradiation and forming the polymer layer, the photocurable resin and the release agent being a combination exhibiting a predetermined turbidity when mixed with each other, and the optical member having a haze of less than 1.0%.
