| abstract |
The present invention relates to an optical polyester film, comprising a polymer primer layer formed on one or both sides of the base film, the polymer primer layer is applied to an acrylic resin and a polyalkylene oxide resin having a carboxyl group, carbodiimide, Transparency by preventing oligomer precipitation due to heat treatment so that it can be used in optical functional coating processes with excellent adhesion and heating process by applying a thermosetting coating solution that crosslinks with one or more crosslinking agents selected from isocyanate and melamine compounds. It relates to an excellent optical polyester film to maintain. |
