PURPOSE: An ultra violet curable composition is provided which has a good scratch resistance, chemical resistance, thermal resistance and solvent resistance, durability of embossing part, shielding property and anti-static property. CONSTITUTION: The composition comprises 30-90 weight % of ultra violet curable acrylateoligomer, 1-30 weight % of ultra violet reactive diluent, 0.1-10 weight % of photopolymerization initiator, 0.05-20 weight % of leveling agent, 0.1-50 weight % of optical property adjusting agent and residue of solvent. Thus, an ultra violet curable composition containing 60 weight parts of 2-functional aliphatic urethane acrylate oligomer, 3 weight parts of methacrylated acidic compounds, 5 weight parts of hydroxy ethyl acrylate, 6 weight parts of alpha-hydroxy-ketone, 1.0 weight part of leveling agent and 10.0 weight parts of polytetrafluoroethylene powder having 0.5 micrometer of average particle size, 1 weight part of anti static agent and 50.0 weight parts of isopropyl alcohol is coated on polyethylene terephthalate film, dried at 50°C for 20 seconds, and irradiated by ultra violet to give the title film.
