摘要： An oriented polyester film is provided according to the present invention which contains, per 100 parts by weight of a polyester,(A) 0.005-2 parts by weight of fine particles having average size of 0.05-3 .mu.m, and(B) 0.005-2 parts by weight of at least one compound selected from the group consisting of high aliphatic monocarboxylic acids having 10-33 carbon atoms and esters thereof.Herein also disclosed is a composite polyester film which comprises a resin layer of copolyester or copolyester ether containing an ester-forming alkali metal salt of sulfonic acid compound, the layer being laminated on at least one side of the oriented polyester film as a substrate. The present invention further provides a magnetic recording medium comprising the oriented polyester film or the composite polyester film as a base.The novel films of the present invention have a surface satisfying three properties: flatness, slipperiness and adhesion, which are considered unable to be attained with a conventional polyester film. Furthermore, a magnetic recording medium having good electromagnetic conversion and running properties can be obtained from the films in the invention.
摘要翻译：本发明提供一种取向聚酯膜，其含有100重量份的聚酯，（A）0.005-2重量份的平均粒径为0.05-3μm的微粒，（B）0.005 -2重量份的至少一种选自具有10-33个碳原子的高脂肪族单羧酸和其酯的化合物。本文还公开了一种复合聚酯膜，其包含含有磺酸化合物的酯形成碱金属盐的共聚酯或共聚酯醚的树脂层，该层被层压在作为基材的取向聚酯膜的至少一面上。本发明还提供一种包含定向聚酯膜或复合聚酯膜作为基底的磁记录介质。本发明的新型薄膜具有满足以往的聚酯薄膜不能达到的三个特性：平坦性，滑溜性和粘着性的表面。此外，可以从本发明的膜获得具有良好的电磁转换和运行特性的磁记录介质。
