Description
本発明は、前記目的を達成すべくなされたものであって、即ち、本発明は、芳香族ジカルボン酸又はそのエステル形成性誘導体を主成分とするジカルボン酸成分と、エチレングリコールを主成分とするジオール成分とを、エステル化反応又はエステル交換反応を経て、少なくともチタン化合物の存在下に重縮合させることにより製造されたポリエステル樹脂であって、２８０℃での射出成形後の成形体における樹脂の環状三量体含有量（ＣＴS；重量％）と、射出成形前の樹脂の環状三量体含有量（ＣＴ0；重量％）との差（ＣＴS−ＣＴ0）が０．１０重量％以下であり、かつ、コバルト化合物の含有量が、ポリエステル樹脂１トン当たり、コバルト原子（Ｃｏ）として１モル以下であるポリエステル樹脂、を要旨とする。 The present invention has been made to achieve the above object, that is, the present invention has a dicarboxylic acid component mainly composed of an aromatic dicarboxylic acid or an ester-forming derivative thereof, and ethylene glycol as the main component. A polyester resin produced by subjecting a diol component to a polycondensation through an esterification reaction or a transesterification reaction in the presence of at least a titanium compound, and the cyclic state of the resin in a molded article after injection molding at 280 ° C. The difference (CT S −CT 0 ) between the trimer content (CT S ; wt%) and the cyclic trimer content (CT 0 ; wt%) of the resin before injection molding is 0.10 wt% or less. der is, and the content of the cobalt compound is, per ton polyester resin, to 1 mole der Ru polyester resin as a cobalt atom (Co), and the gist.
