(57) [Problem] To provide a protective coating function of a reflection film 3 formed on a substrate and an adhesion function of bonding two substrates 1 and 2 with one kind of photocurable resin composition. The protective coating / adhesive layer 7 of the digital video disk (DVD) to be combined is formed. SOLUTION: A photocurable component mainly cured by a polymerization reaction of an unsaturated group, the photocurable component having a bifunctional urethane acrylate, an epoxy acrylate having a bisphenol A skeleton, and a phosphate ester skeleton (meth) The (meth) acrylate containing an acrylate and having the phosphate ester skeleton is present in the range of 0.01 to 0.19% by weight based on the total amount of the photocurable component; The composition having a viscosity at 200C in the range of 200 to 900 mPa ยท s forms the protective coat / adhesive layer 7 of the DVD. |
