COMPOSITE POLYESTER FILMS ESPECIALLY USABLE AS SUPPORTS FOR MAGNETIC RECORDING MATERIAL AND MAGNETIC RECORDING MATERIALS THEREOF |
摘要 |
<p>Composite films comprised of an unloaded semicrystalline polyester film support with a roughness Ra no greater than 0.01 mu m having, on at least one of its faces, a coating based on a modified polymer produced by polymerising one or several acrylic monomers in the presence of a water-dispersable sulphonated copolyester. The composite films according to the invention are particularly well suited as supports for thin magnetic films.</p> |
