摘要： A method of insulating an electrical conductor by applying thereto a coating of a polyesterimide resin which can be hardened through its free OH groups from a resin melt at above 100.degree. C., wherein the resin used is solvent-free and has been prepared by esterification or ester-exchange of starting materials for the polyesterimide in the presence of an excess of one or more short-chain diols and subsequent removal of the diol or diols in such a way that the condensation is only effected to an extent such that the Durrans softening point of the unhardened resin is not above 150.degree. C. (preferably not above 100.degree. C.) and the viscosity of the molten resin at 180.degree. C. is not above 5000 (preferably not above 1000) mPa s (cP). This process avoids the disadvantages encountered when a solvent is present in the insulating bath.

摘要： Diimidodicarboxylic acids for the preparation of polyester resins which in addition to ester groups, contain imide groups between functional groups of the molecule. The imide groups are in the form of 5-membered imide rings resulting from the condensation of, for example, an aromatic carboxylic acid anhydride and a primary amine. The resins can be used in lacquers for production of insulated electrical conductors, with the resin being the film forming component of the lacquers.
