Nano-embossed structure, method for producing nano-embossed structure, and polymerizable material for producing nano-embossed structure

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a nano embossed structure, capable of forming a nano embossed structure consisting of fine uneven structure without performing a complicated etching process, etc., to simply and efficiently manufacture the nano embossed structure.SOLUTION: A method for manufacturing a nano embossed structure comprises the steps of: preparing a polymerizable material including at least one kind of polyfunctional acrylic monomers (A) selected from tetra- to octa-functional acrylic monomers and at least one kind of monomers (B) selected from monomers having 1-3 of the number of functional group having a carbon-carbon double bond, and having 70 mol% or more of the content of the polyfunctional acrylic monomer (A) to the total amount of the polyfunctional acrylic monomer (A) and the monomer (B); forming a film consisting of the polymerizable material; and forming the nano embossed structure on a surface contacting the oxygen of the film by irradiating the film with light in an oxygen containing atmosphere to perform photopolymerization.SELECTED DRAWING: None
