PURPOSE:To provide the titled paint which is insoluble in insulating varnish and has a high electric field-relaxing effect, consisting of a specified modified polybutadiene resin and silicon carbide powder. CONSTITUTION:A polymn. initiator, a hardener and silicon carbide powder are blended with an acrylic-modified, allyl-modified or epoxy-modified polybutadiene resin of formula I , II or III. The mixture is dissolved in a solvent to obtain an electric field-relaxing paint. A sheet-form or tape-form fiber composed of glass fiber or an org. fiber is coated with or immersed in said point to obtain an electric field-relaxing material. EFFECT:Since visible corona starting voltage is high, an electric field-relaxing material excellent in corona deterioration can be obtd. USE:Rotor of a rotary machine, coil end, etc.
