摘要： PURPOSE:To obtain an insulating membrane of an excellent heat-resisting prop erty by using a varnish mainly of a polyester resin including an imido-ring in the molecular structure, and containing acidic phosphor compound in about 0.05 to 3 equivalent % of the excessive alcoholic hydroxide base of the polyester resin. CONSTITUTION:To a polybasic acid such as terephthalic acid, imido-acid (dicarboxylic acid) is added in 60 equivalent % or less to the polybasic compo nent. Furthermore, an alcohol of trihydric or more such as glycerin of 20 to 75 equivalent % or more to the polyhydric alcohol component is added to a dihydric alcohol such as etylene glycol, heated at 100 to 250 deg.C, and the water and the alcohol generated are removed to compose a polyester resin containing imido-sings. By including an acidic phosphor compound such as orthophosphoric acid about 0.05 to 3 wt% to the excessive alcoholic hydroxide base of the polyes ter resin when the resin is composed, it acts as a catalyst for ester reaction. By dissolving the resin in cresol or the like, and spreading and baking on a wire or the like, an insulating membrane of an excellent heat-resisting property and a good adhesive property by the acidic phosphor compound can be obtained.

摘要： PURPOSE:To obtain a water-soluble insulating coating which compares favorably in electrical, mechanical and thermal characteristics with a conventional organic- solvent type insulating coating comprising a polyester containing imido groups, by the addition of a polybasic acid to a specified esterimide resin, followed by neutralization of the adduct with a basic compound. CONSTITUTION:A water-soluble insulating coating prepared by the addition of a polybasic acid containing one anhydride group in a molecule to an esterimide resin of a hydroxyl value of 110-300 and dissolving the adduct in water with a basic compound. Preferably, the esterimide resin is obtained by reacting polyhydric alcohols including at least trihydric alcohol with an imidic acid which contains imido groups and is composed of an aromatic dicarboxylic acid and its derivative, trimellitic anhydride, and a diamine, in the proportion of 1.2-2.1 equivalents of the polyhydric alcohols to one equivalent of the carboxyl group.
