Abstract:
A polarizing film has a transparent protective film provided on at least one side of a polarizer through an adhesive layer. The transparent protective film is a cellulose-based resin film. The adhesive layer is formed by a cured layer obtained by irradiating an active energy ray-curable adhesive composition with active energy rays. The composition contains 0.0% by weight to 4.0% by weight of an active energy ray-curable compound (A) having an SP value of 29.0 (MJ/m3)1/2 to 32.0 (MJ/m3)1/2, 5.0% by weight to 98.0% by weight of an active energy ray-curable compound (B) having the SP value of 18.0 (MJ/m3)1/2 to 21.0 (MJ/m3)1/2 (exclusive of 21.0 (MJ/m3)1/2), and 5.0% by weight to 98.0% by weight of an active energy ray-curable compound (C) having the SP value of 21.0 (MJ/m3)1/2 to 26.0 (MJ/m3)1/2 on a basis of 100% by weight of a total amount of the composition.
