Abstract:
This hard coat film includes a substrate film comprising a thermoplastic resin including an alicyclic structure-containing polymer, and a hard coat layer provided on at least one surface of the substrate film, wherein the number of flaws produced in the hard coat layer when steel wool against which a cylinder with a diameter of 13 mm under a load of 500 gf is pressed is moved back and forth 10 times on the hard coat layer is less than five; when, prior to a light resistance test in which the hard coat layer is irradiated with ultraviolet light for 48 hours, 100 sections each having a size of 1 mm × 1 mm are formed by making notches in the hard coat layer, and a cellophane tape is peeled off within one second after being applied onto the 100 sections, the number R1 of remaining sections of the hard coat layer is 90 or more; and after the light resistance test, the number R2 of remaining sections of the hard coat layer is 90 or more.
