<P>PROBLEM TO BE SOLVED: To provide an optical easy adhesive polyester film which allows inhibition of rainbow color under a fluorescence lamp, and excellent in adhesiveness to a hard coat layer under a high temperature and a high humidity (heat and wet resistance). <P>SOLUTION: The optical easy adhesive polyester film is obtained by coating a water-based coating liquid on at least one side of a biaxially oriented polyester film, drying, and laminating an applying layer which is oriented toward at least one direction, wherein the water-based coating liquid contains a resin composition which is mainly composed of a water polyester resin (A) and at least one (B) of a soluble titanium chelate compound, a soluble titanium acylate compound, a soluble zirconium chelate compound, and a soluble zirconium acylate compound at an (A)/(B) mixing ratio (in mass ratio) of 10/90 to 95/5. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
