Abstract:
A wire having an inner insulating layer and a layer made of a baked enamel applied to the inner insulating layer, the baked enamel comprising a thermoplastic polyamide made of aromatic and aliphatic structures, whose molar ratio of aromatic structure units is 60:40 to 50:50, as well as a cross-linking agent, which includes a multivalent alcohol, a polyisocyanate and a polyol, and the cross-linking period of the baked enamel is large in relation to the drying time of the baked enamel, so that the cross-linking agent does not react or reacts only partially during application and hardening of the baked enamel and the resoftening temperature of the baked enamel is greater than the temperature for baking the baked enamel.
