Description

technical field

[0001] The present disclosure relates to optical polyester films, and more particularly to improving optical polyester films in which at least one side of the polyester base film is coated with a primer layer due to the primer layer being damaged by UV rays during processing. Reduced adhesion to optical polyester films. Background technique

[0002] Polyester films are widely used as industrial materials in various fields as well as display devices because of their dimensional stability, uniform thickness, and excellent optical transparency. In particular, biaxially stretched polyester films are used as base films in various industrial fields because of their dimensional stability, uniform thickness, and excellent optical transparency. Optical polyester films belong to the category of plastic films used for optical purposes along with other films, and are commonly used as components of display devices, such as components of PDP (plasma display, plasma displa...
