INSULATED WIRE AND RESIN DISPERSION

摘要

An insulated wire and a resin dispersion used for a covering layer of the insulated wire are disclosed. The recent tendency to reduction of size of electric/electronic devices requires improvement of electric insulation even in high-temperature environment against the deterioration attributed to generation of heat by constituent parts and to degradation of heat dissipativity. However, conventional insulated wires covered with polyester resin by extrusion coating have not met the requirement adequately. According to the invention, the continuous phase of the resin dispersion meeting the requirement is a polyester resin, and the disperse phase is a resin having a functional group having reactivity with the polyester resin.
