Beschreibung
Zusammenfassung:A polyester resin composition according to an embodiment comprises: a polyester resin; an application agent; and an antioxidant, in which a diol residue includes a cyclohexanedimethanol residue, a dicarboxylic acid residue includes a terephthalic acid residue, and the weight ratio of the application agent and the antioxidant is 1:0.01 to 20. A polyester film according to an embodiment has a b* value of 5 or less in a CIELAB color space after being left at 150℃ for 2 weeks. The polyester resin composition, polyester film, etc., according to the embodiment have excellent properties such as heat resistance, durability, and optical properties, and are used to manufacture a flexible flat cable that requires durability due to repeated exposure to heat, thereby providing a flexible flat cable with superior properties.
