Abstract
본 발명은 자기기록매체용 이축배향 폴리에스테르 베이스 필름에 관한 것으로, 에틸렌테레프탈레이트 또는 에틸렌-2,6-나프탈레이트를 주반복 구조로 하는 이축배향 폴리에스테르 필름이 있어서, 평균입경이 0.01~1.0㎛인 탄산칼슘을 0.01~1.0중량% 함유하며 필름표면돌기 접촉각(θ)이 40°이하임을 특징으로 하는 이축배향 폴리에스테르 베이스 필름.The present invention relates to a biaxially oriented polyester base film for magnetic recording media, wherein the biaxially oriented polyester film having ethylene terephthalate or ethylene-2,6-naphthalate as the main repeating structure has an average particle diameter of 0.01 to 1.0 mu m. A biaxially oriented polyester base film containing 0.01 to 1.0% by weight of phosphorus calcium carbonate and having a film surface projection contact angle θ of 40 ° or less.
