[PROBLEMS] In addition to an optical function, it has excellent interlayer adhesion, is mechanically and chemically stable, has high durability, has good production efficiency, and has a low curling phenomenon, so that the assembly efficiency of a display device or the like is low. Provided are a film having a good hard coat layer and a product to which the film having a hard coat layer is applied. An adhesive strength of a primer layer to a transparent substrate is set to 1 N / cm 2 at room temperature by superimposing a primer layer formed on one surface of the transparent substrate with a thickness of 0.1 to 1 μm and a transparent substrate. 180 degree peeling force based on JIS-Z0237 after pressurizing under pressure is 0.001 to 4N, and the hydroxyl value A (KOHmg / g) of the resin composition before curing of the primer layer is 3 ≦. The primer layer and the hard coat layer are formed on at least one surface of the transparent base material in which A ≦ 50 and the hydroxyl value B (KOH mg / g) of the resin composition before curing of the hard coat layer is 30 ≦ B ≦ 200. It is characterized by being sequentially laminated. [Selection diagram] Fig. 1 |
