Abstract: A polyester film is provided to prevent the attach of the dust on the surface and to control the glossiness of the surface of a film by containing an antistatic film and having enough responsivity of visible light area. A polyester film comprises a base material layer which is made by using a polyester resin and an antistatic coating layer having a surface specific resistance of 3Î1012Ф / □ or less in a relative humidity 50%. The average reflexibility in the wavelength 400~700nm is 90% or greater to one side of a polyester film. The difference of the glossiness(60‹) of one side of the polyester film and the other side is 5~80.
Abstract translation: 提供聚酯膜以防止灰尘附着在表面上并且通过包含抗静电膜并具有足够的可见光面积的响应度来控制膜的表面的光泽度。 聚酯膜包括通过使用聚酯树脂制成的基材层和在相对湿度50%下表面电阻率为3Ω12/□/□或更小的抗静电涂层。 波长400〜700nm的平均反射率在聚酯薄膜的一面为90%以上。 聚酯膜和另一面的一侧的光泽度(60 <)的差异为5〜80。

Abstract: In view of the above problems of the art, it is an object of the present invention to provide a white polyester film which achieves a high reflectivity and a high hiding property simultaneously, and hardly causes a film break and has high productivity. This object can be achieved by a white polyester film containing voids therein, wherein a resin constituting the film has a layer formed by using a polyester resin and a cyclic olefin copolymerized resin, and wherein a ratio of the void in a cross-section of the layer is more than 25% and 75% or less and the average particle size on number of the cyclic olefin copolymerized resin in the film is 0.1 µm or more and 3 µm or less.
