    摘要： 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.

    摘要： A transparent stack structure includes a substrate and a hard coating layer stacked on the substrate. Compressive modulus and elastic restoration of the hard coating layer and the substrate satisfy Formula 1. Mechanical strength may be obtained from the substrate, and flexible and elastic properties may be enhanced by the hard coating layer so that cracks may be prevented when being folded or bent.

    摘要： A hard coating film satisfies the static frictional coefficient of 0.4 or less between an upper surface of a hard coating layer and a back surface of a substrate film, such that it is possible to achieve the hard coating film capable of suppressing a protrusion damage and having excellent anti-blocking properties while providing excellent transparency and hardness, as well as a polarizing plate including the hard coating film, and an image display device including the polarizing plate.
