Biaxially oriented polyester film for a magnetic recording medium |
| abstract |
A biaxially oriented polyester film for a magnetic recording medium, which is formed from a polyester composition comprising at least one member of fine particulate agglomerates selected from the group consisting of alumina fine particulate agglomerates and fine particulate agglomerates of a composite oxide comprising alumina and other metal oxide(s) in a proportion of 0.05 to 1% by weight of the polyester, the fine particulate agglomerates having an average particle diameter of 0.005 to 0.5 μm and having been surface-treated with an alkali metal salt of a polyvalent carboxylic acid; in which the alkali metal salt of a polyvalent carboxylic acid for surface treatment is used in a proportion of 0.05 to 2.0% by weight of the fine particulate agglomerates as an alkali metal atom; and other inert fine particles different from the above fine particulate agglomerates and having an average particle diameter of 0.2 to 2.0 μm in a proportion of 0.05 to 5% by weight of the polyester. |
