Abstract:
Provided is a scratch self-repairing film including a hardcoat layer that has surface hardness, flexibility, and heat resistance at high levels and offers excellent workability. The scratch self-repairing film according to the present invention includes a substrate layer, a hardcoat layer on or over one side of the substrate layer, and a flexible resin layer on or over the other side of the substrate layer. The hardcoat layer includes a cured product of a curable composition. The curable composition includes a cationically curable silicone resin and a leveling agent. The cationically curable silicone resin includes a silsesquioxane unit. The cationically curable silicone resin includes an epoxy-containing monomeric unit in a proportion of 50 mole percent or more of the totality of all monomeric units and has a number-average molecular weight of 1000 to 3000.
