Abstract: A polyester laminate paper with excellent adhesiveness, thermal resistance, moldability and the like as prepared by laminating a polyester resin in a pellet form on at least one of the faces of a paper, the polyester resin containing a butylene terephthalate recurring unit as the main component and satisfying the following conditions (1) and (2): (1) the melt tension thereof at 250° C. is 0.5 to 2.5 mN; and (2) the difference (?IV) between the intrinsic viscosity of pellet surface part IV (S) and the intrinsic viscosity of pellet center part IV (C) is 0.1 or less.

Abstract: A fire retardant polyester resin composition comprising (A) 95 to 30 parts by weight of a polyester resin and (B) 5.0 to 70 parts by weight of a polyphenylene ether resin and/or polyphenylene sulfide resin, and, for 100 parts by weight in total of the components (A) and (B), (C) 0.05 to 10 parts by weight of a compatibilizing agent, (D) 2.0 to 45 parts by weight of a phosphoric ester compound or phosphonitrile compound, (E) 0 to 150 parts by weight of a reinforcing filler, (F) 0.001 to 15 parts by weight of an anti-dripping agent, (G) 0 to 45 parts by weight of a melamine cyanurate, and (H) 0 to 15 parts by weight of a polystyrene resin having epoxy group, provided that the amount of the component (G) is from 0.5 to 45 parts by weight for 100 parts by weight in total of the components (A) and (B) when the amount of the component (B) is less than 35 parts by weight. The polyester resin composition scarcely corrodes a metal mold when it is molded, and is excellent in fire retardancy.
