Document Type and Number:
Japanese Patent JP2003248972
Kind Code:
A
Abstract:
To provide an ultraviolet curing resin composite for an optical disc which enhances light resistance of a silver or silver alloy reflective thin film, protects from being corroded and proves to be highly strong in adhesion.
The ultraviolet curing resin composite for the optical disc is formed on a reflective layer of the silver or the silver alloy which comprises a (1) (meta)acrylate compound with number average molecular weight of 700-3000 derived from epoxy resin, a (2) (meta)acrylate monomer with more than one unsaturated ethylene group, and a (3) polymerization initiator expressed with the following general formula (I).
