PROBLEM TO BE SOLVED: To provide a polyimide film laminate excellent in high surface hardness, scratch resistance, wear resistance, chemical resistance, durability, surface smoothness, and heat resistance.SOLUTION: The polyimide film laminate is formed by laminating a resin layer having a glass transition temperature of 250°C or higher and a polyimide film having a glass transition temperature of 230°C or higher. The resin layer is obtained by curing a photocurable resin composition containing a cage silsesquioxane resin having photocurability. The thickness ratio of the resin layer to the polyimide film (the thickness of the resin layer/the thickness of the polyimide film) is 0.05 to 5.0 inclusive.SELECTED DRAWING: None |
