摘要：A biaxially oriented polyester film which consists of a polyester compositioncomprising 0.001 to 0.03 % by weight of crosslinked polymer particles having an averageparticle diameter dA of 0.8 to 1.6 mu m, 0.1 to 0.8 % by weight of inert particles having anaverage particle diameter dB of 0.4 to 0.8 mu m, and 0.05 to 1.0 % by weight of inertinorganic particles having an average particle diameter dC of 0.01 to 0.3 mu m and aMoh's hardness of not less than 7, and which satisfies the following equations (1) and (2):wherein dA and dB are defined as above, wherein SRz is a three dimensional 10-pointsaverage roughness of a film surface and SRa is a three dimensional center plane averageroughness of a film surface.
