Abstract: A film excellent in heat resistance, dimensional stability to heat, and mechanical properties, especially a film capable of satisfying requirements such as higher strength necessary for base-film thickness reduction, improved dimensional stability to heat and improved mechanical properties in use atmospheres, and enhanced heat resistance and improved dimensional stability to heat which meet the needs of the electrical and electronic fields for size reduction and multi-function. It is obtained by incorporating transition metal oxide particles into a thermoplastic resin and forming the composition into a film which is a biaxially oriented thermoplastic film having a melting point higher than that of the thermoplastic resin used. Preferably, when the biaxially oriented thermoplastic resin film is analyzed with a differential scanning calorimeter (DSC), the difference between the peak temperature for the quantity of heat of fusion in the 1st run (melting point T1) and the peak temperature for the quantity of heat of fusion in the 2nd run (melting point T2) satisfies the following relationship. 2°C ≤ T1-T2 ≤ 30°C Alternatively, the biaxially oriented thermoplastic resin film containing transition metal oxide particles incorporated therein is regulated so as to have a coefficient of in-plane orientation of 0.120 or higher and lower than 0.280.

Abstract: A polyester film which is useful especially as a base film for magnetic recording media such as a cassette magnetic tape for the digital recording system. The film is produced by irradiating with ultraviolet a surface of a film which is in an unstretched stage or is being stretched to thereby form fine projections on the surface. In the film surface, the ratio of the ten-point average surface roughness Rz to the center-line average surface roughness Ra, Rz/Ra, is lower than 20. The film has a specific value of the ratio of the carboxyl group concentration in a surface part to that in an inner part, and further has the fine projections in a specific number.
