STAMPER FOR INJECTION MOLD

摘要

PROBLEM TO BE SOLVED: To provide a stamper made of a resin for an injection mold having a fine uneven shape formed on its surface with high precision, easy to manufacture and having great versatility, and its manufacturing method. SOLUTION: A curable resin composition is injected in a master mold manufactured using a resin composition containing a polypropylene resin and a hydrogenated derivative of a block copolymer represented by formula: X-Y (wherein X is a polymer block incompatible with the polypropylene resin and Y is an elastomeric polymer block of a conjugated diene) and subsequently cured to be molded.
