Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
78 words
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 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.
Claim 2
Independent Claim
78 words
