Abstract

See full text

A hardcoat film includes a base material film and a cured layer disposed on at least one surface of the base material film, in which the cured layer is obtained by curing an active energy ray-curable resin composition, a film thickness of the cured layer is greater than 10 μm, and contains polyrotaxane, inorganic fine particles having an average primary particle diameter of less than 2 μm, and particles having an average primary particle diameter of equal to or greater than 2 μm, and a mass of the particles is equal to or greater than 0.10 g/cm3. In the hardcoat film, both high surface hardness and sufficient surface asperities can be achieved in the cured layer having a large film thickness containing the inorganic fine particles. Also provided are a front plate of an image display element, a resistive film-type touch panel, a capacitance-type touch panel, and an image display.
