    • The present invention provides an insulated wire having a conductor and at least two insulating coating layers formed surrounding the conductor, wherein the insulating coating layers comprises the outermost layer thereof, which has a thickness in the range of 20 to 50% based on the total thickness of the insulating coating layers and comprises a polyimide resin; and a base insulating coating layer in contact with the conductor, which has a thickness in a range of 50 to 80% based on the total thickness of the insulating coating layers and comprises a polyamide-imide resin having an adhesion-improving agent. The insulated wire of the present invention has insulating coating layers having superior coating adhesion as well as good heat-resistance.
    • 本发明提供了一种绝缘电线,其具有导体和围绕导体形成的至少两个绝缘涂层,其中绝缘涂层包括其最外层,其厚度基于总厚度为20至50% 的绝缘涂层,并且包括聚酰亚胺树脂; 以及与所述导体接触的基底绝缘涂层,其基于所述绝缘涂层的总厚度具有在50至80%的范围内的厚度,并且包括具有粘合性改进剂的聚酰胺 - 酰亚胺树脂。 本发明的绝缘电线具有优异的涂层密合性和良好的耐热性的绝缘涂层。
