    摘要： A laminated polyester film for use in a magnetic recording medium, which comprises (A) a first layer of a first polyester which contains at least 95 mol%, based on the total content of its dicarboxylic acid components, of a 2,6-naphthalenedicarboxylic acid component and whose main recurring unit is composed of ethylene-2,6-naphthalenedicarboxylate, and (B) a second layer of a second polyester containing 93 to 99 mol%, based on the total content of its recurring units, of an ethylene-2,6-naphthalenedicarboxylate recurring unit. The second layer is laminated on at least one surface of two surfaces of the above first layer.

    摘要： A unidirectionally long, biaxially oriented film of polyethylene-2,6-naphthalenedicarboxylate:

    (A) which has a Young's modulus of 400 to 600 kg/mm² in the machine direction and a Young's modulus of at least 1,200 kg/mm² in the transverse direction, the ratio of Young's modulus in the transverse direction to the Young's modulus in the machine direction being at least 2.5,
    (B) which has a heat shrinkage of 1 % or less after heat-treated under no load at 105°C for 30 minutes, and
    (C) which has a surface roughness (Ra) of 0.005 to 0.010 µm.

    This film is useful as a base film for magnetic tape having the capacity of log hours' recording and reproduction.
