Abstract: A polyamide resin composition includes 15 to 45 parts by weight of a (B) triazine type compound, 0.01 to 4 parts by weight of a (C) colorant, and 0.01 to 2.0 parts by weight of a (D) dispersant with respect to 100 parts by weight of a (A) polyamide resin, wherein the (C) colorant has a 10% mass loss temperature of not less than 825° C. in thermogravimetric analysis (TGA), and the (D) dispersant has a 10% mass loss temperature of not less than 360° C. in thermogravimetric analysis (TGA). The flame-retardant polyamide resin composition has an excellent product's external appearance, which is excellent in flame retardancy (glow wire property), moldability, and a mechanical property (toughness), and which contains a colorant, and also provides a molded article thereof.

Abstract: The present invention provides a multilayer film comprising five layers, wherein each layer is constituted by a resin having the following density in that order. 1st layer an ethylene &agr;-olefin copolymer having a density of 0.930 to 0.950 g/cm3, 2nd layer: an ethylene-&agr;-olefin copolymer having a density of 0.890 to 0.920 g/cm3, 3rd layer a polypropylene having a density of 0.900 to 0.930 g/cm3, 4th layer: an ethylene-&agr;-olefin copolymer having a density of 0.890 to 0.920 g/cm3, and 5th layer an ethylene-&agr;-olefin copolymer having a density of 0.915 to 0.950 g/cm3, and a container using the same. This container is useful for containing liquid medicine, blood or the like in the medical field.

Abstract: High-strength steel having a tensile strength of 80 kgf/mm.sup.2 or more is produced by one-line quenching or on-line quenching and tempering. The steel has also excellent low-temperature toughness and excellent weldability, which makes high temperature preheating unnecessary prior to welding. The composition is: C=0.04% to 0.11%; Si.ltoreq.1.0%; Mn=0.5% to 2.00%, Mo=0.10% to 1.0%, Nb=0.005% to 0.05% B=0.0009% to 0.0012% Al.ltoreq.0.1%; and N.ltoreq.0.0060%.
