Abstract: PURPOSE:To obtain polyester composition which gives a film excellent in traveling characteristics and abrasion resistance by incorporating specified polyimide particles into a polyester. CONSTITUTION:A polyester comprising, e.g. a homopolyester such as polyethylene terephthalate or a copolyester composed mainly thereof is mixed with polyimide particles having a mean particle diameter of 0.01-3mum and a strength (S10), at 10% deformation under an external force, of 3-30kgf/mm . Examples of the polyimide include those having a structure of any one of formulas I to V. It can easily be produced in particulate for by a known process; i.e. a tetracarboxylic acid anhydride is reacted with a diamine in an appropriate organic solvent to synthesize a polyimide precursor comprising a polyamic acid, and the obtained product is precipitated in a poor solvent for the polyamic acid, such as methanol, to form particles. The amount of the polyimide particles to be incorporated should be 0.01-5 wt.% based on the polyester.
