The present invention relates to an ultraviolet curable composition and a film for whiteboard using the same. The UV curable composition according to the present invention is 30 to 90% by weight of UV curable acrylate oligomer, 1 to 30% by weight of UV reactive diluent, 0.1 to 10% by weight of photopolymerization initiator, 0.05 to 20% by weight An ultraviolet curable composition comprising a leveling agent and a residual amount of a solvent,n n n The oligomer is a six-functional aliphatic urethane acrylate, the ultraviolet reactive diluent is a monofunctional or polyfunctional acrylate monomer or a mixture thereof, and the leveling agent is characterized in that the ultraviolet curable non-silicone compound.n n n The film produced using the UV-curable composition of the present invention is good in scratch resistance, solvent resistance, chemical resistance, heat resistance and the like, the surface hardness is high as 2H level. In addition, since it is excellent in clarity and erasability of the macapen, when used as a film for whiteboard, the whiteboard manufacturing process can be innovatively simple and contribute to productivity improvement. |
