<P>PROBLEM TO BE SOLVED: To provide an easily adhesive polyester film for optical use which suppresses an iris-like hue under a fluorescent lamp, has excellent adhesion with a hard coat layer and excellent adhesion (moist heat resistance) under a high temperature and high humidity condition and reduces the lowering of adhesion even if an easily adhesive layer is exposed to the high temperature and high humidity condition. <P>SOLUTION: At least one side of a biaxially stretched polyester film is coated with a composition prepared by adding a fluorine type surfactant to a resin composition, which contains an aqueous polyester resin (A) and at least one compound (B) among a water-soluble titanium chelate compound, a water-soluble titanium acylate compound, a water-soluble zirconium chelate compound and a water-soluble zirconium acylate compound as main constituent components and is characterized in that the mass ratio of (A)/(B) is 10/90-95/5, in an amount of 0.1-4.0% by mass of the resin component and, after the coated film is dried, a coating layer stretched at least in one direction is laminated on the coated film to obtain the easily adhesive polyester film for optical use. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
