PURPOSE:To obtain a hard coating agent and an adhesive composed of an ultraviolet curing composition, excellent in adhesion to a thermoplastic saturated norbornene-based resin and having high hardness after the curing. CONSTITUTION:The ultraviolet curing composition is composed of a monofunctional acrylate such as n-butyl acrylate or lauryl acrylate, a bi- or a trifunctional acrylate monomer such as hydrogenated tricyclo[5.2.1.0<2>,<6>] decanyl diacrylate, a tetra- or a polyfunctional acrylate such as dipentaerythritol hexaacrylate and a photopolymerization initiator and contains >=40wt.% total amount of a long-chain aliphatic monofunctional acrylate monomer, an alicyclic monofunctional acrylate monomer and an alicyclic bifunctional acrylate monomer. |
