う問題が生じる。(Conventional technology) In recent years, photocurable resins have advantages such as shortening curing time, saving energy, and reducing air pollution.
It is widely applied in fields such as inks, paints, and adhesives. However, compounds containing photopolymerizable double bond gold used in photocurable resin compositions, particularly photopolymerizable double bond-containing compounds that have low molecular weight and low viscosity, have the drawback of being extremely irritating to the skin. As a method for reducing the skin irritation of a photopolymerizable composition, there is a method of using a methacrylate compound, which has a relatively low skin irritation, instead of an acrylate compound, which has a high skin irritation. However, when a methacrylate compound is used, problems may arise in curing time, physical properties of the cured product, etc. because the polymerization rate of the methacrylate compound is slow. Another method is to use a conventional low molecular weight acrylate compound modified with an alkylene oxide such as ethylene oxide or propylene oxide, or a compound modified with an oxyacid such as hydroxypivalic acid. However, when the skin irritation of the resin composition is reduced by using these acrylate compounds with low skin irritation instead of the conventional acrylate compounds with high skin irritation, there is a problem that adhesion and other performances deteriorate. occurs.

らである。(Problem to be Solved by the Invention) When reducing the skin irritation of the coating agent by replacing the highly skin-irritating compound in the composition of the protective coating agent for the metal-deposited surface of an optical disk with a low skin-irritating compound, the coating agent The properties that the agent must have, such as high hardness, high scratch resistance, adhesion to polycarbonate, and good applicability, are reduced. The reason why the protective coating agent for the metal-deposited surface of an optical disk must have adhesive properties to polycarbonate is that the metal-deposited surface of the disk is not entirely coated with metal, but the center and peripheral areas are coated with metal. This is because the polycarbonate is exposed, so by welding at this part, the aluminum surface will be covered and protected.

J / cJと2000mJ/ cJの2通りとした。Example 1 4.5 parts of bisphenol-based epoxy acrylate (trade name Lipoxy 5P1509, Showa Kobunshi In), 56.5 parts of triacrylate (trimethylolpropane adduct with 3 moles of ethylene oxide), hydroxypivalate ester neopentyl glycol di Acrylate 28.3
10.7 parts of 1-hydroquinulfenyl ketone were uniformly mixed to obtain a resin composition. This resin composition was coated on an aluminum plate and a polycarbonate plate to a thickness of about 5 μm by a spin-coding method, and was cured by irradiation with ultraviolet rays. The cured film on the aluminum plate was evaluated for pencil hardness, and the cured film on the polycarbonate plate was evaluated for adhesiveness. In addition, the ultraviolet curing conditions are 1000 m
There were two types: J/cJ and 2000mJ/cJ.
