One side of a substrate film 11 is coated with a coating composition containing (A) a reactive particle produced by chemically bonding an organic compound having at least one polymerizable unsaturated group in its molecule to an inorganic oxide particle, (B) a monomer or oligomer of an organic compound having at least two polymerizable unsaturated groups in its molecule, (C) an organic compound with a weight average molecular weight of at least 1500 and having at least one polymerizable unsaturated group in its molecule, and, if desired, (D) a siloxane compound having a dimethylsiloxane skeleton, and the coating composition is cured by irradiation with ionizing radiation to form a hard coat layer 12 with a thickness of 2 to 20 mum. This provides a hard coat film having adequate surface hardness and suppressed warpage.
