<p>PURPOSE:The titled electric wires that are produced by coating electroconductive wires with a polyhydroxy ether which composed of specific structural units, thus being suitable for use in deflecting yoke coils for motors, because it has good fluidity, lowers costs and shows little deformation after processing. CONSTITUTION:(A) A compound having 2 epoxy groups in the molecule and (B) another compound having 2 phenolic hydroxyls in the molecule, of which at least one has a structural unit of formula I, are allowed to react to give a coating mainly consisting of (C) polyhydroxy ether. The resulting coating is coated directly or after primer coating, on electroconductive wires, the coating is heat- cured, preferably further, electric current is passed through the wires for fusing to give the objective coils. The compound containing the structure of formula I is preferably used more than 25wt% and the compound of component A is that of formula II and component B is that of formula III or IV.</p> |
