Abstract: DISCLOSED IS A BIAXIALLY ORIENTED POLYESTER FILM THAT IS 7.0 GPa OR MORE IN EITHER THE YOUNG''S MODULUS IN THE MACHINE DIRECTION (YmMD) OR IN THE TRANSVERSE DIRECTION (YmTD), AND IN RANGE OF 55o OR MORE AND 85o OR LESS IN THE CIRCUMFERENTIAL HALF-WIDTH OF THE DIFFRACTION LINE FROM THE CRYSTAL PLANE IN THE DIRECTION OF THE POLYESTER''S BACKBONE CHAIN THAT IS DETERMINED THROUGH CRYSTAL ORIENTATION ANALYSIS BY WIDE ANGLE X-RAY DIFFRACTOMETRY PERFORMED WHILE ROTATING THE POLYESTER FILM AROUND ITS NORMAL. THE FILM IS HIGH IN RIGIDITY IN ALL DIRECTIONS WITHIN THE FILM PLANE, HIGH IN TEAR RESISTANCE, HIGH DIMENSIONAL STABILITY, AND RESISTANT TO DEFORMATION UNDER LOAD, AND HAVE VERY GREAT INDUSTRIAL ADVANTAGES AS MATERIAL FOR HIGH-DENSITY MAGNETIC RECORDING MEDIA, WITH WIDE APPLICABILITY AS MATERIAL FOR ELECTROSTATIC CAPACITOR, HEAT TRANSFER RIBBON, AND BASE PAPER FOR THERMOSENSITIVE STENCIL PRINTING.

Abstract: Disclosed is a biaxially oriented polyester film that is 7.0 GPa or more in either the Young's modulus in the machine direction (YmMD) or in the transverse direction (YmTD), and in the range of 55 DEG or more and 85 DEG or less in the circumferential half-width of the diffraction line from the crystal plane in the direction of the polyester's backbone chain that is determined through crystal orientation analysis by wide angle X-ray diffractometry performed while rotating the polyester film around its normal. The film is high in rigidity in all directions within the film plane, high in tear resistance, high in dimensional stability, and resistant to deformation under load, and have very great industrial advantages as material for high-density magnetic recording media, with wide applicability as material for electrostatic capacitor, heat transfer ribbon, and base paper for thermosensitive stencil printing.
