<p>A flame-retardant polyethylene terephthalate resin composition which comprises (A) 100 parts by weight of a polyethylene terephthalate resin, (B) 5 to 60 parts by weight of a bromine compound flame retardant having a 5 wt.% heating loss temperature of 360°C or higher as measured in a nitrogen stream at a heating rate of 10 °C/min, (C) 0.01 to 20 parts by weight of a crystallization accelerator, (D) 0.01 to 20 parts by weight of a colorant, and (E) 0.01 to 5 parts by weight of an antioxidant. The resin composition has high resistance to thermal discoloration. When heated at 210°C for 24 hours, the composition has a color difference ΔE of 15 or less. The resin composition may contain an antimony compound flame retardant aid and/or an inorganic filler. The resin composition can be effectively inhibited from changing in color and can combine mechanical properties with resistance to thermal discoloration.</p> |
