PROBLEM TO BE SOLVED: To obtain a polyester composition, excellent in uniform dispersibility of particles, good in moldability without causing the reaggregation of the particles even when kept in a molten state and capable of providing a film excellent in runnability and abrasion resistance in molding the composition into the film. SOLUTION: This polyester composition comprises an aromatic polyester without substantially any strong acidic group or its metallic salt group, cross- linked polymer particles having >=50% cross-linking degree and a water-soluble high molecular compound. The water-soluble high molecular compound has >=0/15 coverage (s) defined by the formula (s)=wr [(w) is the amount of the added water-soluble high molecular compound (based on wt.% of the polymer particles); (r) is the average radius of the cross-linked polymer particles (μm)]. The film comprising the polyester composition is obtained. |
