PURPOSE: To provide an insulated wire of high processability resistance having an insulation coat of high flexibility and damage resistance by using a specific aromatic diamine compound as the diamine component of a polyamide-imide insulation paint.
CONSTITUTION: Regarding polyamide-imide paint composed of an oxide component containing at least acid chloride and a diamine component, at least one of aromatic diamine compounds expressed by the formulae I, II and III is used as a raw material diamine component by a ratio of 10 to 80mol.% for a total raw material diamine component. R1 in the formula I stands for a hydrogen atom, an alkyl group, an alkoxyl group or a halogen atom, and (n) for a numeral between 1 and 4. R2 and R3 in the formula II stand identically or differently for a hydrogen atom, an alkyl group, an alkoxyl group or a halogen atom, and (p) and (q) identically or differently for a numeral between 1 and 4. R4 and R5 in the formula II are the same as R2 and R3 in the formula II, and (r) and (s) stand identically or differently for a numeral between 1 and 4.
