OPTICAL DISK MANUFACTURING SHEET

摘要

A sheet (1) for manufacturing an optical disk by forming a stamper receiving layer (11) having an energy beam curability and a storage elastic modulus before curing of 103 to 107 Pa and an adhesive layer (12) having an adhesion strength with polycarbonate of 200 mN/25mm or more and a storage elastic modulus of when the stamper receiving layer (11) is cured of 103 to 107 Pa. By using such a sheet (1), separation caused while an optical disk is manufactured and while the product is stored is prevented, and warp of the manufactured optical disk is lessened.
