  • Publication number: 20130337267
    Abstract: The present invention can solve various problems posed by a triacetyl cellulose film, and provides a laminated polyester film which can exhibit a good adhesion property to adhesives as well as a good adhesion property to various surface functional layers, and can be suitably used as a protective film for a polarizing film, in particular, as a protective film disposed on a front surface of a front side polarizing plate. The laminated polyester film according to the present invention comprises a polyester film; and a coating layer formed on one surface of the polyester film which is obtained by applying a coating solution comprising a hydroxyl group-containing polycarbonate compound and an oxazoline compound onto the surface of the polyester film.
