PURPOSE:A composition suitable as an electric laminate, having improved heat resistance, impact resistance, and low-temperature punchability, comprising a blend of a rigid unsaturated polyester component and a non-rigid component and/or a copolymer, and a crosslinkable monomer, wherein the non-rigid component consists of a component except crosslinked rubber. CONSTITUTION:(A) A blend and/or copolymer of (B) a rigid unsaturated polyes ter component and 1-50wt%, especially 5-25wt% based on the composition of a non-rigid component except crosslinked rubber, such as one nor more selected from non-rigid unsaturated polyester, aliphatic polyether, polycaprolactam, and a vegetable oil, and (C) 10-70wt%, especially 20-50wt% based on total amounts of a crosslinkable monomer such as styrene are blended to give a composition. The composition is impregnated into a substrate, plural sheets are laminated, cured continuously under no pressure, to give an electric laminate. The cured material has glass-transition temperatures in -100-0 deg.C low-temperature range and in 100-200 deg.C high-temperature range, and the disper sion diameter consiting of the non-rigid component is <0.4mu.
