Abstract:
Provided are: a polyester resin composition that exhibits excellent flame retardancy and melt thermal stability and also exhibits excellent laser markability; and a method for producing same. The present invention provides: a polyester resin composition containing 3 to 60 parts by mass of a brominated polyacrylate flame retardant (B) relative to 100 parts by mass of a thermoplastic polyester resin (A), this brominated polyacrylate flame retardant (B) having a Na element concentration of 5 to 4000 ppm, as measured by X-Ray fluorescence analysis; and a production method including washing the brominated polyacrylate flame retardant (B) with hot water having a temperature of 40° C. to 100° C., then drying the washed product, and then mixing the dried product with the thermoplastic polyester resin (A).

Claim (Index 1):
A polyester resin composition, comprising:\n (A) 100 parts by mass of a thermoplastic polyester resin (A); and (B) 3 to 60 parts by mass of a brominated polyacrylate flame retardant (B), relative to the 100 parts by mass of the thermoplastic polyester resin (A), wherein the brominated polyacrylate flame retardant (B) has a Na element concentration of 5 to 4000 ppm, as measured by X-Ray fluorescence analysis.
