Abstract

The invention provides a hard coating film, and a window and an image display device including the same. The hard coating film includes a base material and a hard coating layer formed on at least onesurface of the base material. The hard coating layer includes a cured product of a hard coating composition, the hard coating composition contains a fluorine-based UV-curable functional group-containing compound, a dendritic acrylate, a conductive polymer, and a solvent, and contains a specific amount of the conductive polymer, and thus can be applied to a flexible display device, and can simultaneously exhibit hard coating and antifouling properties only with a single-layer structure that does not constitute a separate antifouling layer. Especially, the excellent antifouling effect can be maintained in various environmental changes.

Description

technical field [0001] The present invention relates to a hard coating film and a window and an image display device comprising the hard coating film. Background technique [0002] Hard coatings are used for various display panels, such as liquid crystal display (LCD), plasma display (PDP), cathode ray tube (CRT), electroluminescent display (EL) and other panels for the purpose of surface protection. Such a hard coat film not only imparts hard coat properties to the surface of the object to be protected, but also imparts resistance to marks such as fingerprints and marks, and also imparts the ability to easily remove pollutants when the surface of the object to be protected is contaminated, that is, antifouling. [0003] In particular, touch-screen panels are gaining popularity. The above-mentioned touch-screen panels have the disadvantage that contamination is easily attached because the screen is often exposed and there are many chances of direct contact with fingers or c...
