| 摘要 | A colorless thermoplastic polyester resin composition that can form a molded article with good appearance is provided. More specifically, a thermoplastic polyester resin composition is provided, which has (A) polybutylene terephthalate resin, (B) polyethylene terephthlatae resin, (C) nigrosine dye, and (D) glass fibers. The blending amounts are (A) in the range of 55-86 wt. % and (B) in the range of 14-45 wt. % based on 100 wt. % of a total of (A) and (B). Further, (C) is in the range of 0.1-1.5 parts by weight based on 100 parts of a total of (A) and (B). Preferably, the carboxy terminal groups of (A) is at 25 (eq/t), the intrinsic viscosity of (A) is in the range of 0.60-0.90, and the melting point of (C) is less than 300° C. | ||
