Abstract:
This hard coating film (10) is provided with a hard coating layer (2) on at least one surface of a base material film (1). The base material film is a polyimide film that contains a polyimide resin; and the hard coating layer is formed of a cured product of a photocurable resin composition. Since both of the hard coating layer and the polyimide film contain an ultraviolet absorbent, the hard coating film has high hardness and excellent light resistance. This hard coating film is applicable to a surface protective material that is arranged on the viewing-side surface of an image display panel, or the like.
