<P>PROBLEM TO BE SOLVED: To provide a laminated polyester film for an antireflection film which enhances the contrast of a display in a light place and has sufficient heat resistance. <P>SOLUTION: The laminated polyester film for an antireflection film comprises three layers containing a light absorbent in the internal layer, differences between averages of light transmittances of the polyester film in wavelength ranges of 440-460 nm, 480-500 nm, 520-540 nm, 560-580 nm and 610-630 nm satisfy specific relational expressions, and a transmittance at 380 nm wavelength is ≤5.0%. The polyester film has coating layers on both sides, the coating amount of one coating layer is 0.001-0.05 g/m<SP>2</SP>, and a cross-linker resin is contained in the other coating layer in an amount of 10-50 wt.%. <P>COPYRIGHT: (C)2009,JPO&INPIT |
