Abstract
(a1) 1∼7.9nm의 중심선 평균 조도 RaA,(b1) 15∼400nm의 10점 평균 조도 RZA, (c1) 11∼51의 RZA/RaA를 갖는 제1폴리에스테르 표면 층 및(a2) RaA보다 크고 5∼40nm의 중심선 평균 조도 RaB,(b2) 75∼600nm의 10점 평균 조도 RZB, (c2) 20 이하의 RZB/RaB를 갖는 제2폴리에스테르 표면층을 포함하고, 제1폴리에스테르 표면층과 제2폴리에스테르 표면층 사이에 하기 관계식 :(a1) a first polyester surface layer having a centerline average roughness R aA of 1 to 7.9 nm, (b1) 10 point average roughness R ZA of 15 to 400 nm, (c1) R ZA / R aA of 11 to 51, and ( a2) a second polyester surface layer having a centerline average roughness R aB of 5-40 nm greater than R aA , (b2) 10 point average roughness R ZB of 75-600 nm, and (c2) R ZB / R aB of 20 or less; And between the first polyester surface layer and the second polyester surface layer:
을 만족시키는 2축 배향 적층 폴리에스테르 필름.Biaxially-oriented laminated polyester film which satisfy | fills.
상기 2축 배향 적층 폴리에스테르 필름은 윤활성이 뛰어나고, 고속 권축성, 가공성 및 자기 필름용으로 사용되는 경우, 전자기적 특성이나 뛰어나고, 특히 자기기록매체용 기재 필름으로서 특히 유용하다.The biaxially oriented laminated polyester film is excellent in lubricity and, when used for high speed crimpability, processability and magnetic film, has excellent electromagnetic characteristics and is particularly useful as a base film for magnetic recording media.
