Beschreibung
Zusammenfassung:	A polyester resin composition; (A) which contains (a) a thermoplastic polyester resin, and (b) a carbon black and/or a graphite, and (B) in which the content of the above component (b) is 0.001 to 2 % by weight based on the total weight of the components (a) and (b). The polyester resin composition may further contain (c) a bromine-containing flame retardant, (d) an antimony-containing flame retardant aid and (e) an inorganic filler in addition to the components (a) and (b). This polyester resin composiotion permits marking of fine lines and precise print with a high contrast with a laser light.
