Biaxially oriented polyester film |
abstract |
A biaxially oriented polyester film composed of nan intimate mixture of an aromatic polyester, barium nsulfate particles having an average particle diameter of n0.1 to 10 micrometers, and an alkali metal or alkaline nearth metal salt of a higher fatty acid having 8 to 34 ncarbon atoms. The fatty acid metal salt has a melting npoint in the range of 120 to 320 °C. The biaxially noriented polyester film has substantially no difference nin surface properties such as surface roughness and the ndegree of gloss between its surface and back, and can be nproduced industrially advantageously with high producinbility and excellent operability. |
