Beschreibung
Zusammenfassung:	A laminated film including, at least on one side thereof, a layer (hereinafter referred to as hardening layer) containing a hardening resin, having a total thickness of 1 to 100 µm, having a light transmittance of 70% or more at a wavelength of 400 nm, showing a Young's modulus of 5 GPa or more when applying a nanoindenter to make a 1 µm depression in the thickness direction into the surface of the hardening layer, and undergoing a rate of deformation of 500 ppm or less after applying a stress of 0.5 MPa for 30 minutes. The present invention provides a laminated film that shows a high surface hardness even when being thin to ensure the simultaneous realization of a high surface hardness and a high bending resistance.
