METHOD FOR PRODUCING OPTICAL MEMBER, AND OPTICAL MEMBER

WIPO Patent Application WO/2017/187793

A1

The present invention provides a method for producing an optical member that exhibits superior abrasion resistance, antifouling properties, and adherence between a substrate and a polymer layer. The method for producing an optical member of the present invention includes a process (1) for applying a first resin onto a substrate, a process (2) for applying a second resin onto at least one of the first resin and a mold, a process (3) for pressing the substrate against the mold, with the first resin and the second resin sandwiched therebetween, to form a resin layer having an uneven structure on the surface thereof, and a process (4) for curing the resin layer to form a polymer layer. The surface of the mold is subjected to a mold release treatment using a fluorine-based mold release agent. The first resin contains a resin component. The resin component contains (meth)acrylamides and a hexa- or higher functional urethane prepolymer at prescribed ratios. The second resin contains a monomer having a reactive group, a fluorine-based surfactant, and a fluorine-containing monomer at prescribed ratios.
