  • the laminate of the present invention has a visible light transmittance as low as 50% or less, and the reflection color when viewed obliquely is neutral or blue, particularly as a Low-E glass plate for buildings, and an automobile. It can be suitably used as a Low-E glass plate for windows and Low-E glass for multilayer glass.

Abstract

La présente invention se rapporte à un stratifié ayant une transmissivité de lumière visible relativement faible et a une couleur neutre ou bleu à la place d'une couleur rouge ou violet lorsque l'on observe l'extérieur du stratifié depuis un angle. L'invention concerne un stratifié (1) formé par la stratification en alternance de trois couches d'une couche diélectrique transparente (12, 14, 16) et de deux couches d'une couche d'Ag (13, 15) sur un substrat transparent de sorte que chaque couche d'Ag (13, 15) soit intercalée entre les couches diélectriques transparentes (12, 14, 16). Lorsque les couches d'Ag (13, 15) sont stratifiées depuis le côté de la base transparente dans l'ordre de couche d'Ag (13) (première couche d'Ag) et de couche d'Ag (15) (seconde couche d'Ag), le rapport de l'épaisseur physique de la seconde couche d'Ag (15) par rapport à la première couche d'Ag (13) est de 1,05 ou plus, et la transmissivité de lumière visible du stratifié (1) est de 50 % ou moins.
