PROBLEM TO BE SOLVED: To provide a resin composition for insulating an electric instrument in which when performing the electrical insulation dipping treatment of an electric instrument using the resin composition for insulating an electric instrument, time of a droplet removal process is short, there is little contamination of dryer at a curing process, the sticking tendency of a coil is further high, and which is excellent in wet heat resistance. SOLUTION: The resin composition for insulating an electric instrument comprises: (A) 1-30 pts.mass of an unsaturated epoxy ester resin which is obtained by making a polyepoxide react with anα,β-unsaturated base acid, and further react with an unsaturated dibasic acid; (B) 5-50 pts.mass of dicyclopentenyloxyethyl methacrylate; (C) 0-30 pts.mass of tris(2-acryloyloxyethyl) isocyanurate; (D) 5-30 pts.mass of an acrylate having an acrylic group of three or more functions or a methacrylate having a methacrylic group of three or more organic functions; and (E) 30-90 pts.mass of 2-hydroxyethyl methacrylate. The electric instrument comprises performing the electric insulating treatment of the composition using the dipping treatment method. COPYRIGHT: (C)2011,JPO&INPIT
