摘要: A polyester resin composition includes a copolymer of a polycarboxylic acid component and a polyol component. The polycarboxylic acid component includes terephthalic acid and/or a derivative thereof The polyol component includes ethylene glycol and/or a derivative thereof and 2,2-dimethyl-1,3-propanediol and/or a derivative thereof. A content by percentage of 2,2-dimethyl-1,3-propanediol and/or the derivative thereof is 27 mol % to 55 mol % based on the total amount of the polyol component. The composition has an intrinsic viscosity of 0.5 dl/g to 0.6 dl/g.
