Claims
- 1. A method of electrically insulating wire in electric wiring of automobiles, which comprises covering the wire with an insulating tape or sheet comprising (1) a polyester layer, (2) a polyolefin adhesive layer having a flexural modulus of 500-20,000 kgf/cm.sup.2, and (3) an anchor coat layer between the polyester layer and the polyolefin adhesive layer, wherein the anchor coat layer comprises a silane-modified polyolefin or an organic titanium compound as a main component, to provide insulated wire.
- 2. The method of claim 1, wherein the insulated wire is a flat cable.
- 3. The method of claim 1, wherein the polyolefin adhesive is a member selected from the group consisting of (1) an ethylene copolymer, (2) a polyethylene grafted with a carboxylic acid, (3) a polyethylene grafted with a carboxylic acid anhydride, (4) a polypropylene grafted with a carboxylic acid, (5) a polypropylene grafted with a carboxylic acid anhydride, (6) a grafted copolymer of an ethylene copolymer with an alkoxysilane, (7) a grafted copolymer of an ethylene copolymer with an unsaturated carboxylic acid, (8) a grafted copolymer of an ethylene copolymer with an unsaturated carboxylic acid anhydride, and (9) a grafted copolymer of an ethylene copolymer with an ionomer.
- 4. The method of claim 1, wherein the flexural modulus of the polyolefin adhesive layer is 1,500-15,000 kgf/cm.sup.2.
- 5. The method of claim 4, wherein the flexural modulus of the polyolefin adhesive layer is 2,500-10,000 kgf/cm.sup.2.
- 6. An insulated wire comprising a conductor, a polyester layer, a polyolefin adhesive layer having a flexural modulus of 500-20,000 kgf/cm.sup.2 interposed between the conductor and the polyester layer, and an anchor coat layer between the polyester layer and the polyolefin adhesive layer, wherein the anchor coat layer comprises a silane-modified polyolefin or an organic titanium compound as a main component.
- 7. The insulated wire of claim 6, which is a flat cable.
- 8. The insulated wire of claim 6, wherein the polyolefin adhesive is a member selected from the group consisting of (1) an ethylene copolymer, (2) a polyethylene grafted with a carboxylic acid, (3) a polyethylene grafted with a carboxylic acid anhydride, (4) a polypropylene grafted with a carboxylic acid, (5) a polypropylene grafted with a carboxylic acid anhydride, (6) a grafted copolymer of an ethylene copolymer with an alkoxysilane, (7) a grafted copolymer of an ethylene copolymer with an unsaturated carboxylic acid, (8) a grafted copolymer of an ethylene copolymer with an unsaturated carboxylic acid anhydride, and (9) a grafted copolymer of an ethylene copolymer with an ionomer.
- 9. The insulated wire of claim 6, wherein the flexural modulus of the polyolefin adhesive layer is 1,500-15,000 kgf/cm.sup.2.
- 10. The insulated wire of claim 9, wherein the flexural modulus of the polyolefin adhesive layer is 2,500-10,000 kgf/cm.sup.2.
