Abstract

A transparent laminated product comprising a transparent substrate and a 5-layered transparent coating composed of a first transparent oxide layer formed on the substrate, a second Ag layer formed on the first transparent oxide layer, a third first transparent oxide layer formed on the second layer, a fourth Ag layer formed on the third transparent oxide layer and a fifth transparent oxide 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 A, and each transparent oxide layer comprises a material selected from the group consisting of SnO₂, Sn_1-x Zn_x O_y, and TiO₂.
