The present invention provides an optical easy adhesive polyester film with inhibited iris color under fluorescent lamp, and exhibits excellent properties of tight adhesion to a hard coating layer, and also tight adhesion at high temperature and high humidity (i.e., wet heat resistance). The said optical easy adhesive polyester film of the invention is characterized in that the said film is produced by using a water-base coating solution with a resin composition comprising (A) water-soluble polyester resin, and (B) at least one compound selected from water-soluble titanium chelate compound, water-soluble titanium acylate compound, water-soluble zirconium chelate compound and water-soluble zirconium acylate compound as main constituents, wherein the mixing ratio (mass ratio) of (A)/(B) is from 10/90 to 95/5, to coat on at least one surface of the biaxial extended polyester film, and after drying, the coated laminate is extended toward at least one direction. |
