Abstract
A hard coating film comprises a substrate, and a hard coating layer formed on at least one surface of the substrate, wherein the hard coating layer is formed from a hard coating composition comprising a hydroxyl group-containing light-transmitting resin, a fluorine-based UV-curable functional group-containing compound, a photoinitiator, and a solvent, and when measured by X-ray photoelectron spectroscopy (XPS) on a surface of the hard coating layer, atomic percent of elemental fluorine (F) on the surface of the hard coating layer is 10 to 55 at %. The hard coating film uses a hard coating composition including a hydroxyl group-containing light-transmitting resin and a fluorine-based UV-curable functional group-containing compound to control the atomic percent of the elemental fluorine (F) on the surface of the hard coating layer to a specific range, thereby providing excellent antifouling properties together with good wear resistance, scratch resistance, and bending resistance.
