To provide a laminated polyester film that can solve a variety of problems possessed by a triacetylcellulose film, is favorable in adhesiveness with an adhesive, high in full-light transmittance, and can suitably be utilized as a protective film of a polarizing film, in particular, a protective film (film D) at a rear side of a rear side polarizing plate.
The laminated polyester film is characterized in that a coating layer containing a hydroxyl-group containing acrylic resin, a polyvinyl alcohol and an oxazoline-based compound is formed at one face of the polyester film, and a coating layer which has one extremely small value in a range that an absolute reflection ratio is 300 to 800 nm in wavelength, and whose extremely small value is ≤3.5% is formed at the other face.
