Multilayer structure sheet and method for manufacturing same, and optical information recording medium and method for manufacturing optical information recording medium using multilayer structure sheet

摘要

A multilayer structure sheet for manufacturing an optical information recording medium having a multilayer structure with a plurality of recording layers is disclosed. The multilayer structure sheet comprises at least one unit structure in which a pressure sensitive adhesive layer, a recording layer, a recording layer support layer having a glass transition temperature higher than that of the pressure sensitive adhesive layer, and a recording layer are laid one on top of another in this order, and a release sheet is attached to an outside of an outermost pressure sensitive adhesive layer.
