多層構造シートとその製造方法、光情報記録媒体および多層構造シートを用いた光情報記録媒体の製造方法

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.
