OPTICAL DISK MANUFACTURING SHEET

摘要

PROBLEM TO BE SOLVED: To provide an optical disk manufacturing sheet wherein a void defect hardly takes place on a rugged pattern transposition face of a hardened stamper receptor layer.

SOLUTION: The optical disk manufacturing sheet 1 is formed by stacking a stamper receptor layer 11 with energy ray curing property and a storage elastic rate before curing of which is 103to 106Pa and an exfoliation sheet 12 with an exfoliation layer 122 a residual adhesion rate of which is 85% or over on at least one side of the stamper receptor layer 11.
