Document Type and Number:
Japanese Patent JP2012209000
Kind Code:
A
Abstract:
To provide a multilayer optical recording medium manufacturing sheet, a multilayer structure for an optical recording medium and a multilayer optical recording medium that can realize both control of transfer of recording materials from an optical recording layer to an adhesive layer and control of warpage.
A multilayer optical recording medium manufacturing sheet 1 is formed by laminating an optical recording layer 11 and an adhesive layer 12. The adhesive layer 12 is formed by an adhesive that consists primarily of (meta) acrylic ester copolymer containing 60 to 100 mass% of aromatic monomer as a component. A glass transition temperature Tg of the adhesive is -30 to 15°C.
