SHEET FOR MANUFACTURING OPTICAL RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a sheet for manufacturing an optical recording medium in which a stamper receptive layer is not peeled off from a layer adjacent to the stamper receptive layer when the cured stamper receptive layer is separated from a stamper. SOLUTION: This sheet 1 for manufacturing an optical disk is composed of the stamper receptive layer 11 of an energy-ray curing type on which the ruggedness of the stamper S is transferred and peeling sheets 12, 12', adhesive power after the curing of the stamper receptive layer 11 for a reflection layer 3 is larger than adhesive power after the curing of the stamper receptive layer 11 for the stamper S, a difference between both adhesive power is 50mN/25mm or more.
