<p>PROBLEM TO BE SOLVED: To provide an optical laminated polyester film using an easily-adhesive polyester film having excellent adhesiveness and appearance and preferably having good adhesiveness even in a moisture-heat environment.SOLUTION: The optical laminated polyester film comprises an easily-adhesive polyester film having a coating layer on at least one surface, and at least one functional layer selected from a hard coat layer, light-diffusing layer, prism-type lens layer, electromagnetic wave absorbing layer, near-infrared shielding layer, and transparent conductive layer, laminated on the coating layer of the film. The coating layer comprises a polyester resin and a block isocyanate as essential components, in which the block isocyanate has a dissociation temperature of 130°C or lower, and a blocking agent in the isocyanate has a boiling temperature of 180°C or higher.</p> |
