Abstract
A sheet () for manufacturing an optical disc which includes a pressure-sensitive adhesive layer (), having a peak temperature of a loss tangent not higher than −10° C. and a polar component (γs) of the surface energy not smaller than 2.0 mJ/m, and a protective sheet (), is laminated on a data recording layer () (a laminate formed of a reflecting layer (), a dielectric layer (), a phase change layer () and a dielectric layer (')) that is formed on an optical disc substrate (). The sheet for manufacturing an optical disk () allows obtaining an optical recording medium that is provided with the pressure-sensitive adhesive layer () that has high adhesion to the data recording layer () and does not peel readily off adjacent layers.
