摘要：
Disclosed is an electrical insulating laminated paper prepared by a process which comprises the steps of melt-extruding a polyolefin resin as a binder onto one or two sheets of a kraft insulating paper by means of a extruder to obtain a laminated paper, and calendering or supercalendering the laminated paper so that the total thickness thereof is from 30 to 200 &mgr;m and the proportion of a polymer comprising the polyolefin resin is from 40 to 90%. The laminated paper is excellent in dielectric properties, dielectric strength, and mechanical properties such as adhesive strength.
