The invention relates to a protection film for optics and manufacturing method thereof, and a polarization plate and manufacturing method thereof. Provided is a protection film for optics, which is in particular suitable for being used as a polarization plate, has excellent transparency, optical isotropy, good moisture resistant, excellent endurance, and good sealing performance with a polarizing film, and has the hard coating function, as well as the polarization plate using the same. The protection film for optics is a laminated film formed by laminating a hard coating (A), a resin layer (B) and a sticker layer (C) in order, each layer contains more than 80 % by weight of (methyl) acrylic acid ester compound, the polarization plate is obtained by laminating the sticker layer (C) of the protection film on one surface of the polarizing film, furthermore, and laminating a sticker layer (D) and a resin layer (E) on the other surface of the polarizing film, moreover, the polarizing film is formed from the sticker layer (D) and the resin layer (E) each containing more than 80 % by weight of (methyl) acrylic acid ester compound. |
