| abstract | PURPOSE: To prepare a polyester film which has an excellent ink receptivity, does not change in the receptivity with the elapse of time, is not discolored during thermal processing, and has an excellent transparency by compounding a specific polyester copolymer with a specific silica powder. n CONSTITUTION: A polyester copolymer comprising 95-98.5mol% structural units derived from terephthalic acid or a deriv. thereof and ethylene glycol and 1.5-5mol% structural units derived from isophthalic acid or a deriv. thereof and at least one glycol selected from diethylene glycol and neopentyl glycol is compounded with 0.01-0.1wt.% silica powder having a mean particle diameter of 0.5-3μm and formed into a polyester film, which has a haze of 6% or lower, a coefficient of dynamic friction of 0.35-0.6, a breaking strength of 20kg/mm 2 or higher, and a Young's modulus of 400kg/mm 2 or higher. The sue of the copolymer overcomes problems, such as degradation in strengths or coloration, accompanying conventional techniques while maintaining the characteristics inherent in polyethylene terephthalate, such as transparency, mechanical characteristics, dimensional stability, and resistance to heat, weather and chemicals, and improves the affinity with an ink. The compounded powder roughens the surface of the film to further improve the ink receptivity. n COPYRIGHT: (C)1992,JPO&Japio |
