<P>PROBLEM TO BE SOLVED: To provide a UV curable resin composition which allows an optical disk having a reflection film composed of silver or a silver alloy to have high durability and light resistance. <P>SOLUTION: The UV curable resin composition for the optical disk contains a sulfur containing compound (A) represented by formula (1), a photopolymerizable compound (B) and a photopolymerization initiator (C). In formula (1), R<SP>1</SP>to R<SP>4</SP>may be the same or different and each denotes a hydrogen atom, an alkyl group, an aryl group, a group represented by -NR<SP>5</SP>R<SP>6</SP>(wherein R<SP>5</SP>and R<SP>6</SP>each denotes a hydrogen atom, a 1-5C alkyl group or a phenyl group), or a group represented by -NR<SP>7</SP>CNR<SP>8</SP>R<SP>9</SP>(wherein R<SP>7</SP>to R<SP>9</SP>each denotes a hydrogen atom, a 1-5C alkyl group or a phenyl group and may be equal to or different from each other) and either one of R<SP>1</SP>and R<SP>2</SP>and either one of R<SP>3</SP>and R<SP>4</SP>may form a ring. <P>COPYRIGHT: (C)2009,JPO&INPIT |
