METHOD FOR PRODUCING PLATE FOR OPTICAL MEMBER, METHOD FOR PRODUCING ROLL PLATE FOR OPTICAL MEMBER, AND OPTICAL MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a plate for optical members, which plate can allow an accurate rugged part to be formed when an optical member having a rugged pattern is produced and can further allow a minute rugged part to be formed on at least a part of the surface of the rugged pattern.SOLUTION: A method for producing an original plate comprises the steps of: exposing a substrate and a resist layer of a laminate, which has the resist layer and is used for producing the original plate; and removing the resist layer in an exposed portion or an unexposed portion to form a resist pattern. At the exposing step, the resist layer is exposed so that incident light on the resist layer is made to interfere with reflected light which the incident light reflects and returns to form a standing wave. A method for electroforming the original plate comprises the steps of: stacking an electroless plating layer on the resist pattern-formed surface by electroforming without etching the original plate; and stacking an electrolytic plating layer on the electroless plating layer.SELECTED DRAWING: Figure 2
