1. A low-emissivity transparent laminate comprising:
a substrate; and a coating layer,wherein the coating layer has a multilayer structure comprising a first dielectric layer, a low-emissivity electroconductive layer, a second dielectric layer, a light absorption metal layer, and a third dielectric layer in a sequential order from the substrate;wherein the low-emissivity transparent laminate has a difference in visible light reflectance from 50% to 75% between one surface thereof at a substrate side and the other surface thereof at a light absorption metal layer side;wherein the light absorption metal layer has a thickness from 15 nm to 25 nm,wherein the low-emissivity electroconductive layer is Ag,wherein the light absorption metal layer is, alloys of Ni and Cr,wherein the first dielectric layer and the third dielectric layer comprises at least one selected from the group consisting of titanium oxide, zinc tin oxide, zinc oxide, zinc aluminum oxide, tin oxide, bismuth oxide, silicon nitride, silicon aluminum nitride, and combinations thereof,wherein the second dielectric layer is zinc aluminum oxide,wherein the substrate is a transparent substrate having a visible light transmittance from 90% to 100%,wherein the first dielectric layer and the third dielectric layer are both outermost surfaces of the coating layer. |
