Title:
窓ペイン用の圧縮応力を加えることのできる低E多層系
Document Type and Number:
Japanese Patent JP2004526650
Kind Code:
A
Abstract:
A multilayer film, capable of withstanding high thermal stresses, with silver as functional layer, a sacrificial metal layer placed on top of the silver layer and antireflection dielectric layers, has a metal nitride layer between the silver layer and the sacrificial metal layer. This metal nitride layer is composed in particular of Si3N4 and/or AlN and constitutes an effective diffusion barrier. The optical and energy properties of the silver layer consequently remain, for the most part, preserved, even after undergoing high thermal stresses (for example of the bending or toughening type when curving and/or prestressing a window pane provided with the multilayer film).
