Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
130 words
A laminated structure comprising: a) a copper metal substrate layer; b) a first adhesive resin layer comprising a first metal ion containing ionomer; c) a second adhesive resin layer comprising a second metal ion containing ionomer, said second metal ion being different from the first metal ion; and d) a polyimide polymer layer, said layers each comprising two major surfaces, the laminated structure being arranged such that one major surface of the copper metal substrate layer is in contact with the first major surface of the first adhesive resin layer, the remaining surface of which is in contact with the first major surface of the second adhesive resin layer, and the remaining surface of the second adhesive resin layer is in contact with a major surface of polyimide polymer layer.
Claim 2
Dependent Claim
130 words
