Abstract: PURPOSE:To obtain the title composition capable of obtaining fibers or films of excellent travelability and wear resistance, esp. suitable for magnetic tapes by incorporating a thermoplastic polyester with spherical vaterite-type calcium carbonate particles. CONSTITUTION:The objective composition can be obtained by incorporating (A) 100 pts. wt. of a thermoplastic polyester made up of (1) a carboxylic acid component predominant in an aromatic dicarboxylic acid and (2) a glycol component predominant in an aliphatic glycol with (B) 0.01 - 10 pts. wt. of vaterite- type calcium carbonate having >= 30 m /g in the specific surface area determined by the BET adsorption technique, 0.01 - 5mum in mean particle diameter and 0.3 - 0.52 in the view factor (f) of the equation (V is particle volume mum ; D is maximal diameter mum of the projected area of particle), prepared by blowing carbon dioxide in calcium hydroxide in an alcoholic solvent to once convert into an amorphous gelled product, which is then put to regulation for particle shape, particle size distribution, and particle diameter, etc.

Abstract: PROBLEM TO BE SOLVED: To provide a biaxially stretched polyester film for molding excellent in environmental properties, dimensional stability, printability and moldability. SOLUTION: The biaxially stretched polyester film for molding is formed from a polyester film comprising a polyester containing an ethylene terephthalate unit and/or an ethylene naphthalate unit as a main constituent. The melting point of this polyester film is not less than 245 deg.C and the stress at the time of 200%-stretching at 80 deg.C and heat shrinkage factor thereof are specified.

Abstract: PROBLEM TO BE SOLVED: To provide a polyester film being pliable, excellent in surface properties (scarcely having a diehead streak), suitable for molding and processing of a high degree, excellent also in moldability, pliability and beauty on the occasion of being laminated with a metallic or non-metallic material, and usable suitably for many materials for molding. SOLUTION: The polyester film is constituted of a polyester composition containing an ethylene glycol-series polyester A, a butanediol-series polyester B and an organic component C (except particulate matter) other than these polyesters in specified ranges, or it is a laminated film comprising a layer of that film as one layer at least. The number of streak-like matters extending in the longitudinal direction of the film on the surface thereof, the width of the film, a surface orientation coefficient of the film and the thickness thereof are within specified ranges.
