The invention provides a flame-retardant resin composition characterised in that it comprises (A) an aromatic polyester prepared by condensation polymerization between (a) a component substantially comprising an aromatic dicarboxylic acid or an ester-forming derivative thereof and (b) a component substantially comprising an aliphatic diol or an ester-forming derivative thereof,
(B) 0.1 to 30% by weight based on the total amount of the composition of a compound represented by the general formula (1) or (2)
wherein X represents a halogen atom; Y₁ and Y₂ each represent a group selected from hydroxyl, carboxyl, glycidyl ester and glycidyl ether groups; Z is a monovalent or divalent organic group and n is an integer of 1 or more and
(C) 0.1 to 30% by weight based on the total amount of the composition of a compound represented by the general formula (3):
L₁-M-L₂ (3)
wherein M is a divalent organic group L₁ and L₂ may be the same or different from each other and each represent a 3- to 8-membered cyclic reactive group selected from those having the general formulae (4) to (7):
in which each of R₁, R₂ and R₃ represent a divalent organic group wherein a hydrogen atom directly bonded to the ring may be substituted with an alkyl and/or aryl group.
The invention also includes electric wires coated therewith.
