POLYESTER RESIN COMPOSITION AND POLYESTER FILM USING SAME

摘要

Provided are a polyester resin composition and a polyester film using thereof, and more particularly, a polyester resin composition including a polyester resin and silica particles coated with a metal compound to prevent an inner defect due to particle agglomeration, and have an excellent surface property of the film, low haze, and an improved transparency, thereby being appropriate for a release film and an optical film for an electronic material, and a polyester film using thereof.

主权项

1. A polyester resin composition comprising:
a polyester resin and a silica particle coated with a metal compound, wherein the silica particle satisfies the following equation 1 and a circumferential angle of the silica particle from any three points at Pmax is 85 to 90 degrees:
0.9≦Pmin/Pmax≦1.0  [Equation 1] (In Equation 1, Pmin is a minimum diameter of the silica particle, and Pmax is a maximum diameter of the silica particle.)
