<P>PROBLEM TO BE SOLVED: To provide a laminated polyester film for antireflection film which improves the bright part contrast of a display when disposed on the uppermost surface of an electronic display, and has a sufficient heat resistance even in case mounted on a film type optical filter. <P>SOLUTION: The laminated polyester film for the antireflection film composed of at least three layers contains a light absorber and an ultraviolet absorber in its inner layer and has the coating layers provided on both sides thereof in a film manufacturing method and characterized in that the average value (Tave) of light transmittances at a wavelength of 400-650 nm is 25-80% and light transmittance (Tuv) at a wavelength of 380 nm is 5.0% or less. The coating amount of one side coating layer is 0.03-0.5 g/m<SP>2</SP>, and the other side of coating layers contains 10-50 wt.% of a crosslinking agent resin. <P>COPYRIGHT: (C)2009,JPO&INPIT |
