Abstract: Embodiments of invention provide a method for producing a hard coat film which has a hard coat that is formed from an active energy ray-curable resin composition on at least one surface of a film base. According to at least one embodiment, the active energy ray-curable resin composition used in this method contains (P) 100 parts by mass of a urethane (meth)acrylate compound, (Q) 0.02-5 parts by mass of organic fine particles having an average particle diameter of 10-300 nm, and (R) 0.0002-2 parts by mass of an acrylic silicone-based leveling agent. The method according to at least one embodiment includes the steps of (1) forming a wet coating film by applying the active energy ray-curable resin composition to the film base, (2) forming a dry coating film by drying the wet coating film, and (3) forming a hard coat film by curing the dry coating film by means of active energy ray irradiation at a temperature of 50-90° C.

Abstract: Embodiments of the invention provide a hard coat film, including a film base material and a hard coat arranged on at least one surface of the film base material, wherein the hard coat is comprised of an active energy ray-curable resin composition. The active energy ray-curable resin composition includes 100 parts by mass of (P) a urethane (meth)acrylate compound, 0.02 to 5 parts by mass of (Q) organic fine particles having an average particle size of 10 to 300 nm, and 0.0002 to 2 parts by mass of (R) an acrylic silicon leveling agent. The (R) acrylic silicon leveling agent is loaded in the active energy ray-curable resin composition in an amount of 1 part by mass or more based on 100 parts by mass of the (Q) organic fine particles.
