Claim Text:
1. A resin composition for wire coating, comprising: (A) 100 parts by weight of a thermoplastic polyester resin (component A) having a terminal carboxyl group concentration of not more than 20eq/ton and an intrinsic viscosity of 0.7 to 1.4 dl/g; (B) 40 to 150 parts by weight of a polyester block copolymer (component B) obtained by carrying out a transesterification reaction between 50 to 90 wt % of a soft segment (component B-1) and 50 to 10 wt % of a hard segment (component B-2) and having an intrinsic viscosity of 0.6 to 1.1 dl/g and a melting point of 190 to 230° C., the component B-1 comprising equal mole of (i) an acid component and (ii) a diol component, (i) the acid component consisting of 15 to 40 mol % of an aliphatic dicarboxylic acid component having 6 to 12 carbon atoms (component B-1-1) and 85 to 60 mol % of isophthalic acid (component B-1-2) and (ii) the diol component consisting of an aliphatic α,ω-diol having 6 to 12carbon atoms (component B-1-3), and The component B-2 comprising equal mole of (i′) an acid component and (ii′) a diol component, (i′) the acid component consisting of terephthalic acid (component B-2-1) and (ii′) the diol component consisting of an aliphatic α,ω-diol having 2 to 4carbon atoms (component B-2-2); (C) 0.1 to 10 parts by weight of a polycarbodiimide compound having a softening temperature of 50° C. or higher (component C); (D) 10 to 50 parts by weight of magnesium hydroxide having an average particle diameter of 0.1 to 2 μm (component D); (E) 0.5 to 5 parts by weight of an inorganic porous filler having an average particle diameter of 0.1 to 1 μm (component E), wherein the component E is at least one selected from the group consisting of fired kaolin, zeolite, mesalite, anthracite, foamed perlite and activated carbon; (F) 0.002 to 2.5 parts by weight of a hindered phenol-based antioxidant (component F); and (G) 0.002 to 2.5 parts by weight of a phosphorus-based antioxidant (component G).
