Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
91 words
A transparent laminated product comprising a transparent substrate and a coating composed of transparent oxide and silver layers alternately laminated in a total of (2n + 1) (n≥2) layers with the inner most and outer most layers being transparent oxide layers and having a surface resistance of at most, 10 Q/sq. and a visible ray transmission of at least 60%, wherein said transparent oxide layer comprises ZnO or Zr0 2 , and the thickness of said silver layer is in a range from 6 to 12 nm (60 to 120 Å)
Claim 2
Dependent Claim
91 words
