<p>There is provided an ultraviolet curing resin composition for an optical disk such as to improve the light resistance of reflective thin films made of silver or silver alloy and protect them against corroding and perform a high adhesive strength, in the optical disks. The composition comprises (1) a (meth)acrylate compound having a number average molecular weight of 700 to 3000 derived from epoxy resin, (2) a (meth)acrylate monomer having one or more of unsaturated ethylene groups, and (3) a polymerization initiator, such as 2,2-dimethoxy-2-phenylacetophenone, benzoylethyl ether and benzoylisobutyl ether, represented in the following general formula (I). Also, a tetrazole derivative may be additionally mixed into the composition. <CHEM></p> |
