Abstract

본 발명은 폴리에스테르 필름에 첨가되는 활제로서 세타알루미나와, 경질탄산칼슘 및/또는 구상실리카를 함께 사용하여 필름의 표면특성, 내마모성 및 내스크래치성 등을 개선하는 동시에 고분자수지로 표면 처리하여 자성체와의 접착성을 개선한 폴리에스테르 필름에 관한 것이다. 즉, 폴리에스테르 중에 적어도 2종류의 불활성 입자를 첨가하여 적어도 일축배향시킨 폴리에스테르 필름에 있어서, 상기 불활성 입자로서 평균입경이 0.005 내지 3㎛이고 모스경도가 6이상인 세타 알루미나를 폴리에스테르 총중량에 대하여 0.01 내지 4% 첨가하고, 평균입경이 0.01 내지 3㎛인 경질 탄산칼슘 및 평균입경이 0.1 내지 1㎛인 구상실리카중 적어도 하나를 폴리에스테르 총중량에 대하여 각각 0.01 내지 4% 하고, 필름의 적어도 일면을 수분산이 가능한 고분자수지로 표면처리한 것을 특징으로 하는 폴리에스테르 필름은, 표면 평활성이 우수하고 특히 내마모성 및 내스크래치성이 월등하게 개선되는 동시에 자성체와의 접착성이 개선되므로 특히 자기기록 매체용으로 사용하기에 적합하다.The present invention improves the surface properties, abrasion resistance and scratch resistance of the film by using theta alumina, hard calcium carbonate and / or spherical silica as a lubricant added to the polyester film, and at the same time surface-treated with a polymer resin to form a magnetic material and It is related with the polyester film which improved the adhesiveness of. That is, in a polyester film in which at least two kinds of inert particles are added to a polyester and at least uniaxially oriented, theta alumina having an average particle diameter of 0.005 to 3 µm and a Mohs hardness of 6 or more is 0.01 to the total weight of the polyester as the inert particles. To 4%, at least one of hard calcium carbonate having an average particle diameter of 0.01 to 3 mu m and spherical silica having an average particle diameter of 0.1 to 1 mu m, each 0.01 to 4% based on the total weight of the polyester, and at least one side of the film The polyester film, which is surface-treated with a dispersible polymer resin, has excellent surface smoothness, particularly excellent wear resistance and scratch resistance, and improves adhesion to a magnetic material, and thus is particularly used for magnetic recording media. Suitable for
