Abstract
본 발명은 필름의 표면 특성 및 내스크래치 성을 개선한 폴리에스테르 필름에 관한 것으로, 폴리에스테르 중에 적어도 2종류의 미립자 A 및 B를 함유하여 되는 이측 배향 폴리에스테르 필름에 있어서, 입자 A는 평균입경이 0.1 내지 3um이며 모스경도가 6이하인 탄산칼슘이고, 입자 B는 평균입경이 0.005 내지 5um이며 모스경도가 6이상인 건조성 실리카인 것을 특징으로 하는 폴리에스테르 필름은, 건조성 실리카 대신 콜로이달 실리카나 알루미나를 첨가한 종래의 필름보다 표면특성, 특히 내스크래치성이 월등하게 개선되므로, 자기 기록 매체용 외에도 그라픽, 스탬핑 호일, 전기절연재료 및 포장용 등과 같이 내스크치성이 중요한 문제가 되는 용도에서 유효하게 사용될 수 있다.The present invention relates to a polyester film having improved surface properties and scratch resistance of a film, wherein in the two-sided polyester film containing at least two types of fine particles A and B in polyester, the particle A has an average particle diameter. The polyester film is 0.1 to 3 um, calcium carbonate having a Mohs hardness of 6 or less, and particle B is a dry silica having an average particle diameter of 0.005 to 5 um and a Mohs hardness of 6 or more. Surface properties, especially scratch resistance, are significantly improved compared to conventional films added with, so that it can be effectively used in applications where scratch resistance is an important problem such as graphics, stamping foils, electrical insulating materials and packaging, as well as for magnetic recording media. Can be.
