Abstract: PURPOSE:To obtain the title composition which can give a white film excellent in whiteness, covering power and dulness, by adding specified amounts of CaCO3 of a specified particle diameter, inorganic particles of a specified particle diameter and a phosphorus compound to a specified polyester. CONSTITUTION:5-50wt.% CaCO3 of a mean particle diameter of 0.05-5mum, 0.01-10wt.% (not inclusive) inorganic particles (e.g., SiO2) other than CaCO3, of a mean particle diameter of 0.06-10mum, and 100-5,000ppm (in terms of P atoms) of a phosphorus compound (e.g., trimethyl phosphate) are added to a polyester comprising at least 80mol.%, based on the total repeating units, ethylene terephthalate. Thus a polyester composition which is freed of agglomerated particles, has a high whiteness, is less yellowish and cannot be obtained heretofore can be obtained. This composition can give a white film excellent in whiteness, covering power, and dulness and can be desirably used as a base for sensitive papers, X-ray-sensitive papers, cards, labels, display boards, white boards, decorative use, etc.

Abstract: PURPOSE: To obtain a polyester compsn. which gives a thermosensitive stencil paper excellent in punchability in a low-energy area and excellent also in dis tinctness of printing by compounding a polyester, a polyoxyalkylene glycol having a specified number average mol.wt., and particles having a specified average particle size. CONSTITUTION: This compsn. comprises a polyester, a polyoxyalkylene glycol having a number average mol.wt. of 200-5,000,000, and particles having an average particle size of 0.01-7.0μm. The content of the polyoxyalkylene glycol of 0.01-50wt.% is suitable. Any kind of particles, inorg. or org., may be used if the particle sizes are in the above-mentioned range, and the content of 0.01-10wt.% is pref. Thus obtd. compsn. gives a stencil paper excellent in punchability (sensitivity to punching and independence of punched holes) in a low energy area and also excellent in distinctness of printing (in character printing and solid printing).
