A hard coating composition is provided to impart high transparency, high hardness, and heat resistance to the surface of transparent polymer plastic. A hard coating composition includes 1-30wt% of polyfunctional acrylate oligomer, 5-40wt% of polyfunctional acrylate monomer, 5-40wt% of polyfunctional phosphazene-based monomer, 0.1-10wt% of a light initiator, and the balance of a solvent. The polyfunctional acrylate oligomer is one or their mixture selected from urethane acrylate, polyester acrylate, epoxy acrylate, silicon acrylate, acrylic acrylate, melamine acrylate oligomer, or mixtures thereof. The light initiator is 1-hydroxy-cyclohexyl-phenyl-ketone. |
