PURPOSE: An optical polyester film with a primer layer is provided to improve productivity in post processing by minimizing interference. CONSTITUTION: An optical polyester film comprises a polyester base film and a primer layer. The polyester base film has the thickness of 50-500 micrometer. The primer layer is applied on at least one side of the base film. The primer layer comprises acrylic polymer, water-dispersible polyester copolymer or polyurethane resin, and inorganic particles. The adhesive force between the primer layer and the base film is 95% or greater.
