| titleOfInvention | Biaxially oriented polyester film |
| abstract | PURPOSE:To make it possible to improve the surface strength and dimensional stability of a biaxially oriented polyester film comprising a polyester, a polyolefin and inert inorganic particles by specifying the molecular weight, crosswise strength at break and average height of protrusions on either surface. CONSTITUTION:This biaxially oriented polyester film is based on a composition comprising 90-99.8wt.%, particularly, 95-99% polyester (A) mainly consisting of ethylene terephthalate units, 0.2-10wt.%, particularly, 1-5wt.% polyolefin (B), desirably, polypropylene and 0.3-1.5wt.%, particularly, 0.4-0.8wt.% inert inorganic particles (C), desirably, colloidal silica of a mean particle diameter of 0.15-1.2mum prepared by the alkoxide process, wherein an Mn of component B is 6000-30000, desirably, 10000-27000, an Mw/Mn ratio <=4.0, desirably, 3.0-1.3, a crosswise elongation at break >=50%, desirably, >=80% and an average protrusion height on at least either surface is 20-500nm, desirably, 40-200nm. This film is desirable as a magnetic recording medium. |
