| titleOfInvention | Polyester resin |
| abstract | A polyester resin obtained by using an aluminum compound and a phosphorous compound as a polymerization catalyst, containing greater than or equal to 85 mol% of an ethylene terephthalate structural unit, wherein the content of an aluminum-based contaminant is less than or equal to 100 ppb, and the content of a phosphorous compound represented by the following structure (B) is 5 to 11 ppm, with respect to the mass of the polyester resin, wherein the content of the aluminum-based contaminant and the content of the phosphorus compound represented by the following structure (B) are determined according to the methods indicated in the description, wherein the phosphorus compound represented by (B) is a product of thermolysis at the time of polymerization of polyester using as catalyst an aluminum compound and a phosphorus compound represented by the following chemical formula (A): **(See formula)** (where in (Formula A), X1 and X2 represent n each containing hydrogen, an alkyl group having 1 to 4 carbon atoms, or a metal having a valence greater than or equal to 1), and wherein the polyester resin has a Tc1 greater than or equal to 170°C and a Tc2 less than or equal to 175°C, where Tc1 and Tc2 are determined according to the method indicated in the description, where Tc1 is the crystallization temperature at the time of raising the temperature, and Tc2 is the crystallization temperature at the time to lower the temperature. |
