[Problem];A method by which a flame proofing property can easily be provided to polyester fiber having long-term stable color and excellent mechanical properties, particularly, a resin composition and a flame proofing method needed for flame retardant spun-dyed polyester fiber which is excellent in light resistance and durability, and is capable of coloring any of various colors, and also, is environment-friendly, are strongly desired.;□Solution□;There is provided a flame retardant spun-dyed polyester fiber obtained by melt-spinning a flame retardant polyester resin composition comprising a flame retardant comprising at least one inorganic phosphorus-nitrogen based compound selected from the group consisting of ammonium polyphosphate, melamine polyphosphate and phosphazenes; colorant; and thermoplastic polyester resin, characterized in that content of said inorganic phosphorus-nitrogen based compound is 0.1 to 12% by mass, content of said colorant is 0.01 to 5% by mass, and content of said thermoplastic polyester resin is 83 to 99.89% by mass, based on the total weight of said polyester resin composition. Particularly, when disposed polyester is used as the thermoplastic polyester resin, it contributes to material recycle as well.
