<p><P>PROBLEM TO BE SOLVED: To provide polyamideimide resin insulating paint capable of providing an insulation film which has the partial discharge inception voltage equal to or higher than that of the conventional insulation film at normal temperature and the partial discharge inception voltage of which is hardly lowered even in a high-humidity environment. <P>SOLUTION: The polyamideimide resin insulating paint is obtained by mixing an isocyanate component (D) in a prepolymer, which is obtained by reacting an acid component, that comprises aromatic tricarboxylic anhydride (A) and aromatic tetracarboxylic dianhydride (B), with a diamine component (C). A mixing ratio of the aromatic tricarboxylic anhydride (A) with the aromatic tetracarboxylic dianhydride (B) is 50/50 to 10/90 ((A)/(B)) by the molar ratio. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
