| 摘要 |
The present invention enables to provide a highly durable protective coating film or adhesive layer for high-density optical disks with less warp, which is superior in transmission for blue lasers, transparency and low water-absorption, by using an ultraviolet-curing resin composition essentially comprising a compound (A) represented by the following general formula (I), [Chemical Formula 7], (wherein, R represents each independently a hydrogen atom or a C1-C3 alkyl group, and n and m each represents the number of repetition from 0 to 5) and a photopolymerization initiator.
