<p>PURPOSE: A hard coating film is provided to obtain excellent mechanical properties such as high scratch resistance, chemical resistance, and scratch resistance, to have a self-healing function, and to minimize the curling of a film while having high strength. CONSTITUTION: A hard coating film comprises a hard coating layer including a crosslinked material between a polyrotaxane compound and a binder resin. The polyrotaxane compound comprises a cyclic compound in which a lactone-based compound with introduced 40-70 mol% of a (meth)acrylate compound is coupled to the terminal of the cyclic compound; a linear molecule which penetrates through the cyclic compound; and a blocking group which prevents the separation of the cyclic compound by being disposed at both terminal of the linear molecule. The cyclic compound includes one or more selected fromα-cyclodextrin,β-cyclodextrin, andγ-cyclodextrin.</p> |
