SHEET FOR MANUFACTURING MULTI-LAYER OPTICAL RECORD MEDIA, MULTI-LAYER STRUCTURE FOR OPTICAL RECORD MEDIA AND MULTI-LAYER OPTICAL STRUCTURE

摘要

PURPOSE: A sheet for manufacturing multi-layer optical record media, a multi-layer structure for optical record media, and a multi-layer structure medium are provided to control movement of recording materials from an optical recording layer to a bonding layer, thereby reducing crosstalk and lowering of recording sensitivity. CONSTITUTION: An optical recording layer(11) and a bonding layer(12) are laminated on a sheet for manufacturing multi-layer optical record media. The bonding layer is made of an adhesive whose free surface energy is smaller than 20mJ/m^2. The adhesive is made of a polymer of fluorine monomers and/or a monomer of a polysiloxane frame. The bonding strength of the adhesive is 500 to 50,000mN/25mm.
