The present invention relates to an ultraviolet curable hard coating composition. In one embodiment, the ultraviolet curable hard coating composition comprises (A) 100 parts by weight of an aliphatic urethane acrylate oligomer having 6 or more polymerizable functional groups, (B) 5 to 20 parts by weight of a benzotriazole modified urethane acrylate oligomer, (C) 5 to 15 parts by weight of a polycarbonate-modified urethane acrylate oligomer, (D) 0.01 to 2 parts by weight of an oxidation stabilizer and (E) 1 to 10 parts by weight of a photopolymerization initiator, (F) 40 to 70 parts by weight of a polyfunctional acrylate monomer (D) 5 to 20 parts by weight of an ultraviolet absorber (G) and 1 to 10 parts by weight of a (H) light stabilizer, wherein the antioxidant (D) Wherein the (B) polyfunctional acrylate monomer is a mixture of a bifunctional acrylate monomer and a trifunctional acrylate monomer in a weight ratio of 1: 1.5 to 2, and the bifunctional acrylate monomer is a mixture of 1, 6-hexanediol Diacrylate, and the trifunctional acrylate monomer is trimethylolpropane triacrylate. |
