Abstract

PURPOSE: To provide a polyester film having fine and irregular surface roughness, and suitable for a tracing material and an electrical material, by treating a polyester film containing fine particles having specific size, with a specific solvent.
CONSTITUTION: A polyester film (e.g. a glycol terephthalate polymer wherein more than 70% of the recurring unit is 2W18C glycol) containing 0.1W10wt% (pref. 0.2W8wt%) of fine particles (e.g. silica powder) having an average particle diameter of ≤0.1 micron (pref. ≤0.05 micron), is treated with a solvent (e.g. alkaline aqueous solution) which dissolves or decomposes the film to dissolve or corrode the surface of the film. The treatment is controlled to give a film having more than 5 (pref. more than 10) protrusions having height range of 0.15W0.7 micron per 10 microns length.
