| titleOfInvention | Biaxially oriented laminated polyester film |
| abstract | (57) [Summary] (Corrected) [Purpose] Excellent recovery of the forcibly stretched tape, It provides a film with little recording distortion and output fluctuation, and good runnability and audio characteristics. A biaxially oriented laminated polyester film for use as a base film of a digital audio cassette tape, wherein the polyester A layer and the polyester B layer are at least two outermost layers, and the biaxially oriented laminated polyester film is 5% in the longitudinal direction of the laminated film. The stress during extension is 12 kg / mm 2 or more, and the residual elongations in the longitudinal direction and the transverse direction are both 0. 2% or less, the thermal shrinkage in the longitudinal direction when heat-treated at 105 ° C. for 30 minutes under no load is 1.5% or less, the total thickness of the film is 12 μm or less, and the surface of the A layer is a magnetic layer. The surface roughness Ra of the A layer surface is 1 to 8 and the surface roughness Ra of the B layer surface is 10 to 4 A biaxially oriented laminated polyester film having a thickness of 0 nm. |
