摘要：
An oriented polyester film (A') which comprises modified polyethylene-2,6-naphthalenedicarboxylate containing a glycol component derived from a compound represented by the following formula,
wherein each of n and m is independently a positive number of 1 to 9 as an average, provided that m + n equals 2 to 9 as an average.
and having a heat of crystallization of 6 to 20 Joule/g, and (B) which is biaxially oriented.
These films are useful as a base film for a magnetic recording tape or as an electric insulation film.
