PROBLEM TO BE SOLVED: To propose a scattering-preventive film that can sufficiently prevent reflection, has satisfactory rework performance features, and is difficult to come off the object to which the film is stuck.SOLUTION: On one face of a base 5 formed of a transparent film material, minute projections 7 are arranged closely to one another at intervals of not greater than the shortest wavelength of a wavelength band for preventing reflection. On another face of this base 5, a strong pressure-sensitive adhesive layer 8A, a core material 9 formed of a transparent film material, and a weak pressure-sensitive adhesive layer 8B, weaker than the strong pressure-sensitive adhesive layer 8A in pressure-sensitive adhesion, are successively disposed. The strong pressure-sensitive adhesive layer 8A is not less than 10 N at a 25-mm width and not more than 20 N at a 25-mm width in the force of peeling from a glass plate in a 180-degree peeling test as prescribed under JIS K6854-2, while the weak pressure-sensitive adhesive layer 8B is not less than 4 N at a 25-mm width and not more than 15 N at a 25-mm width in the force of peeling from a glass plate in the 180-degree peeling test as prescribed under JIS K6854-2. |
