PURPOSE: An ultra violet curable composition is provided which has a good scratch resistance, chemical resistance, thermal resistance and solvent resistance and embossing durability, 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 and residue of solvent. Thus, an ultra violet curable composition containing 70 weight % of 3-functional aliphatic urethane acrylate oligomer, 15.0 weight % of trimethylolpropane triacrylate, 3 weight % of methacrylated acidic compounds, 5 weight % of hydroxy ethyl acrylate, 6.0 weight % of alpha-hydroxy-ketone, 1.0 weight % of leveling agent and residue 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. |
