ABSTRACT:
The invention provides a coating composition comprising a thermal plastic resin selected from the group consisting of a polycycloolefin resin, polyester resin, polyacrylate resin, and a mixture thereof; and a radiation curable resin comprising a radiation polymer containing at least one mono- or multi-functional acrylic acid based monomer as a polymerization unit, an oligomer containing an ethylenically unsaturated functional group, and a photoinitiator, wherein the radiation curable resin is used in an amount of 220-1000% by weight on the basis of the weight of the thermal plastic resin. The invention improves the hardness of the coating composition, prevent the coated substrate from being scratched or impaired, and impart the substrate with high transparency without causing warping problem.
