BIAXIAL ORIENTIERTE POLYESTERVERBUNDFOLIE |
摘要 |
<p>A biaxially oriented laminated polyester film comprising a first polyester layer which contains two different types of inert fine particles having different average particle diameters and has a surface roughness of 4 to 15 nm and a second polyester layer which may contain inert fine particles and has a surface roughness of 0.5 to 3.5 nm. The film has a friction coefficient between the first polyester layer and the second polyester layer of 0.5 or less and a good roll form. A cover layer may be further formed on the second polyester layer. The film can be used as a magnetic recording medium by forming a magnetic layer on the second polyester layer or the cover layer overlying the second polyester layer. <IMAGE></p> |
