Abstract
An imido-modified unsaturated polyester resin composition comprising an imido-modified unsaturated polyester obtainable by reacting an animal or vegetable fat and oil or a fatty acid thereof, an imido alcohol obtainable from a primary amino-alcohol and a polybasic acid anhydride, a polyhydroxy alcohol, and a polybasic acid in such a manner that the imido alcohol is used in an amount of 10 to 60% equivalent amount based on the alcoholic components; and a polymeric monomer. In one of the preferred embodiments, the composition according to the present invention further contains an inorganic filler. According to the present invention, there can be provided resin composition in which the compatibility under heat deterioration when used in enamelled wires has been improved, while maintaining excellent electrical and mechanical properties. When the present resin composition further contains an inorganic filler, not only compatibility under heat deterioration but also the thermal conductivity and corona-resistance have been improved.
