(該式中,Sb及S分別形成聚二甲酸伸烷酯之全二羧酸成份,代表具有銻化合物及酯形成性官能基之磺酸4級鏻鹽化合物單位之莫耳比(單位為mmol%)者。
本發明之薄膜具有優異之表面平坦性,適於磁性記錄媒體用基礎薄膜。且,具有優異之高速卷取性、可安定製膜,有利於工業之製造。
A polyalkylene naphthalate for a film, which comprises a naphthalenedicarboxylic acid component as a main dicarboxylic acid component and an aliphatic glycol component as a main glycol component, and contains (a) an antimony compound and (b) a quaternary phosphonium sulfonate compound unit having an ester-forming functional group in such amounts that satisfy the following expressions (1) and (2): 0 < Sb <= 80, 0 < S/Sb <= 0.4, respectively, wherein Sb and S are the molar ratios (mmol%) of the antimony compound and the quaternary phosphonium sulfonate compound unit having an ester-forming functional group to the total dicarboxylic acid components from the polyalkylene naphthalate, respectively. The film of the present invention has excellent surface flatness and is suitable for use as a base film for a magnetic recording medium. It is also excellent in high-speed winding properties and can be formed into a film stably and advantageous industrial production.
