| titleOfInvention | Biaxially Oriented FILM OF POLYETHYLENE-2, 6-NAPHTHALENEDDICARBOXYLATE of Polyethylene-2,6-naphthalenedicarboxylate |
| abstract | (A) has a Young's modulus of at least 800 kg / mm2 in the longitudinal direction, a Young's modulus at least 500 kg / mm2 in the transverse direction, Young's modulus in the longitudinal direction is greater than the Young's modulus in the transverse direction, (B) 1 kg / The relationship between the elongation S M (%) in the longitudinal direction and the Young's modulus Y M (kg / mm 2) in the longitudinal direction at 120 ° C. per load of mm 2:n n n If Y M is 1,200 kg / mm 2 or less,n n n -0.001 Y M +0.89 <S M <-0.001 Y M +1.57n n n If Y M is more than 1,200 kg / mm 2,n n n -0.31 <S M <0.37n n n And (C) a polyethylene-2,6-naphthalenedicarboxylate biaxially oriented film having a heat shrinkage ratio of 0.1% or less in the longitudinal direction when the biaxially oriented film is heat treated at 70 ° C. under specific load for 1 hour. This film has little dimensional change, has high strength in the longitudinal direction, is excellent as planarity, and is useful as a base film for magnetic recording media capable of high density recording for a long time. |
