A UV radiation curable coating composition comprising (A) of 20 to 60% by weight of a urethane acrylate oligomer, (B) of 20 to 60% by weight of a UV radiation curable monomer, (C) of 1 to 10% by weight of an organic solvent and (D) from 1 to 10% by weight of a photoinitiator in relation to the total weight of the composition, in which the urethane acrylate oligomer has 6 to 9 functional acrylate groups and has a viscosity of 500 to 30,000 cps (centipoise) at 25 ° C. |
