an adhesive surface of the masking film on the hard-coat layer side has surface free energy of 30.0 (mN/m) or more prior to being affixed, as calculated from the average contact angle of water and the average contact angle of diiodomethane according to the OWRK method;
the hard-coat layer is curable;
the surface roughness Sa of the adhesive surface of the masking film is 0.1 μm or less; and
an adhesive layer of the masking film on the hard-coat layer side comprises polyurethane.
