TECHNOLOGY FOCUS - POLYMERS - Preferred Process: The fluorine-containing resin containing fluorine group copolymer resin and polyvinylidene fluoride, is added to the resin layer, to improve compatibility. The adhesive resin having aziridinyl group, is obtained by copolymerizing aziridinyl group-containing compound and compound having copolymerizable vinyl group.Preferred Resin: The fluorine group copolymer resin is ternary polymer resin oftetrafluoroethylene-hexafluoropropylene-vinylidene fluoride. The non-fluorine-containing resin contains acrylic-type resin and/or polycarbonate-type resin.Preferred Property: The composition ratio rate of fluorine-containing resin and non-fluorine-containing resin is 60-95:5-40 wt.%, and composition ratio rate of tetrafluoroethylene-hexafluoropropylene-vinylidene fluoride in fluorine-containing resin is 50% or more.Preferred Film: The fluorine group film comprises 5-20 wt.% of white pigment. EXAMPLE - Tetrafluoroethylene-hexafluoropropylene-vinylidene fluoride copolymer (in wt.%) (75) having tetrafluoroethylene content of 55%, fluoropropylene content of 20 wt.% and vinylidene fluoride content of 25 wt.%, and Dianal BR-80 (RTM: copolymer of methyl methacrylate and methyl acrylate) (acrylic-type resin) (25), were molded to form fluorine-resin film having thickness of 100 micrometers. Methyl methacrylate (45), 2-(1-aziridinyl)ethyl methacrylate (5), azobisisobutyronitrile (0.2), toluene (34.8) and isopropanol (15) were reacted at 85degreesC in nitrogen atmosphere for 7 hours. Toluene/isopropanol solution was added to the reaction mixture, to obtain adhesive resin having aziridinyl group-containing compound content of 10 wt.%. The adhesive resin was applied on the surface of fluorine-resin film, and dried at 100degreesC for 3 minutes to form adhesive resin layer having thickness of 0.5 micrometers. Thus, electrical and electronic insulating sheet was obtained. The sheet had tearing force of 4.5 N measured according to JIS P 8116, favorable weather resistance and damp-proof property, measured according to JIS C 8917 and adhesive power measured according to JIS K 6328.
