ABSTRACT:
A layer for protection coating and adhesion of DVD is formed by a photo-curing resin composition which comprises a photo-curing component which is cured by polymerization reaction of a unsaturated group, a photo-polymerization initiator and a phenol-based primary antioxidant, wherein this photo-curing component comprises a bi-functional urethane acrylate, an epoxy acrylate containing a bisphenol A skeleton, and a N-vinyl lactam compound, said polymerization initiator comprising a mono or di-benzoylphosphine oxide compound in an amount of 0.1% by weight or more to less than 5.0% by weight based on the total amount of said photo-curing components, and the viscosity of this resin composition at 25.degree. C. being in the range from 350 to 700 mPa.multidot.s.
