摘要： Disclosed is a biaxially oriented film and a laminated film containing specified organic particles at a content of 0.001 to 20% by weight. The strength when deformed by 10% (S.sub.10) of the organic particles is in the range of 3 to 30 kgf/mm.sup.2, the thermal decomposition temperature for causing 10% loss in weight thereof is not lower than 350.degree. C. The weight average diameter thereof is in the range of 0.005 to 5 .mu.m. Since the organic particles have a good affinity with the matrix resin of the film and a good thermal resistance and the hardness of the particles is appropriate, desired protrusions hardly chipped and having an appropriate hardness for hardly scratching a magnetic surface can be formed on a film surface easily and uniformly. Therefore, a film excellent in abrasion resistance and scratch resistance at a high running speed and excellent in running durability can be obtained, which is useful particularly as a base film of a magnetic tape.

摘要： The invention is a polyester composition containing crosslinked polymer particles with ester bonds at the main chain. The particles are excellent in affinity to polyesters, and so the films formed from the polyester compositions do not have the particles falling off during high speed running, and do not have flaws in the film surfaces. The invention can prevent the generation of white powder and the flaws of magnetic faces caused by falling-off particles, and prevent the contamination in the production of films, even though these are problems caused when various conventional particles are added, and is especially suitable for use as products such as magnetic films.
