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.

Hard coating film and image display device having the same

The present invention provides a hard coating composition comprising a dendrimer compound having a terminal (meth)acrylate group, a polyhedral oligomeric silsesquioxane compound, a photoinitiator and a solvent; a hard coating film formed using the same; and an image display device having the hard coating film. The hard coating film according to the present invention can minimize the occurrence of curling while having excellent hardness, scratch resistance and bending resistance.
