PURPOSE:To provide the title compsn. which can form a self-lubricating film excellent in lubricity and abrasion resistance and free from degradation in the properties during a high-temp. high-speed baking and to provide an enameled wire using the compsn. CONSTITUTION:An arom. diisocyanate. a lactam, and a polycarboxylic acid having an acid anhydride group are reacted in an equivalent ratio of the lactam to the diisocyanate of 20-90% in the presence of a cresol solvent to give a polyamide resin sol. in the solvent. 100 pts.wt. the resin, 0.1-10 pts.wt. partially saponified ester wax, and 0.1-10 pts.wt. low-mol.-wt. polyethylene having a number-average mol.wt. of 5,000 or lower are compounded. |
