PROBLEM TO BE SOLVED: To provide a self-adhesive film which is suitable for a film for window, which can be slided to be positioned between the self-adhesive film and an adherend when the film is adhered increasing the adhesive force with lapse of time after adhering and can be adhered firmly to the adherend.SOLUTION: There is provided a self-adhesive film 1 comprising an adhesive layer 3 on a film base material 2. The adhesive layer comprises a crosslinked product formed by an adhesive polyurethane and 0.1 to 13 pts.mass of an aziridine-based cross-linker based on 100 pts.mass of the adhesive polyurethane. The adhesive polyurethane is a polyurethane obtained by chain-extending a prepolymer, which is obtained by reacting a diol that is formed by condensing an alkanediol having 4 to 8 carbon atoms and adipic acid with a diisocyanate, with a diamine.SELECTED DRAWING: Figure 1 |
