<p>The present invention relates to an optical polyester film, and, more specifically, to an optical polyester film by which, when an optical function layer such a prism or optical diffusion layer is formed on a polyester film, an adhesion force and moisture resisting adhesion force of a polyester film base material and the optical function layer are excellent, transmissivity and optical properties such as haze and the like are excellent, and a blocking phenomenon in which adhesion is generated between coating layers by a combination between unreacted molecules in the coating layer or water permeation, can be prevented.</p> |
