[Problem] To provide a nucleating agent-containing polyester resin composition that accelerates crystallization of a polyester resin, that enables production of, at high productivity without causing a plate-out, a polyester resin molding capable of maintaining high transparency even after crystallization, and that can be used in a wide range of use applications. [Solution] A polyester resin composition containing 100 parts by mass of a polyester resin, 0.01-10 parts by mass of a 2-amino-1,3,5-triazine derivative represented by formula [1], and 0.01-10 parts by mass of a fatty acid having 14-30 carbon atoms, and a polyester resin molded object obtained through crystallization of the polyester resin composition (in the formula: R1 and R2 each independently represent -C(=O)R5, -C(=O)OR6, -C(=O)NR7R8, or -SO2R9; R3 and R4 each independently represent a hydrogen atom, an alkyl group having 1-6 carbon atoms, -C(=O)R5, -C(=O)OR6, -C(=O)NR7R8, or -SO2R9; R5, R6, and R9 each independently represent an alkyl group having 1-20 carbon atoms or a phenyl group optionally substituted with an alkyl group having 1-6 carbon atoms; and R7 and R8 each independently represent a hydrogen atom, an alkyl group having 1-20 carbon atoms, or a phenyl group optionally substituted with an alkyl group having 1-6 carbon atoms). |
