PHOTOCURABLE SHEET AND OPTICAL INFORMATION RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To obtain an optical information recording medium improved in the corrosion resistance of a light reflective layer such as of silver or its alloy provided on a substrate and excellent in reliability/durability, and to provide a photocurable sheet to be suitably used in laminating substrates for such an optical information recording medium.

SOLUTION: The photocurable sheet is made from a photocurable composition containing a reactive polymer having photopolymerizable functional groups. This sheet also contains a polymerization inhibitor and/or antioxidant encapsulated in microcapsules. The optical information recording medium is obtained by mutually bonding optical information recording substrates through this sheet.
