Abstract

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 Ω/sq. and a visible ray transmission of at least 60%.

Claims

1. A transparent laminated product comprising a transparent substrate and a 5-layered transparent coating composed of a first ZnO layer formed on the substrate, a second Ag layer formed on the first layer, a third ZnO layer formed on the second layer, a fourth Ag layer formed on the third layer and a fifth ZnO layer formed on the fourth layer, and having a visible ray transmission of at least 60%, wherein the thickness of each Ag layer is from 60 to 250 Å
