TRANSPARENT LAMINATE HAVING LOW EMISSIVITY

Title:

TRANSPARENT LAMINATE HAVING LOW EMISSIVITY

Document Type and Number:

WIPO Patent Application WO/2002/026488

Kind Code:

A1

Abstract:

A transparent laminate having low emissivity which has one or more dielectric layers such as a zinc oxide (ZnO) film and one or more metal layers such as a silver (Ag) film being laminated on one another, characterized in that at least one dielectric layer is divided in the direction of film thickness by at least one amorphous layer. The transparent laminate having low emissivity exhibits improved durability of the metal layer, since the formation of a zinc oxide film as a dielectric layer on an amorphous layer causes the collapse of the columnar crystal structure of zinc oxide and, as a result, not only the amorphous layer but also the dielectric layer act also as a barrier preventing the entry of moisture or a gas.
