    摘要: Provided are: a polarizer protective film, which is allowed to express excellent UV-absorbing ability by using a UV-absorbing monomer as a raw material, has excellent heat resistance and excellent optical transparency, and has much less coloring and foaming; a polarizing plate with less defects in an outer appearance, using the polarizer protective film; and an image display apparatus of high quality, using the polarizing plate. The polarizer protective film of the present invention has a light transmittance at 380 nm in a thickness of 80 μm of 30% or less, and is obtained by molding a forming material that contains a resin component containing as a main component a (meth)acrylic resin obtained by polymerizing a monomer composition containing a UV-absorbing monomer and a (meth)acrylic monomer by extrusion molding.
