Abstract

Le problème décrit par la présente invention est de fournir un moyen permettant de réduire la dépendance d'angle de la couleur d'un film bloquant les IR comprenant un diélectrique multicouches. La solution de l'invention porte sur un film bloquant les IR contenant un substrat et un diélectrique multicouches agencé sur au moins une surface dudit substrat, lesdits diélectriques multicouches comprenant une alternance de couches à indice de réfraction élevé et de couches à faible indice de réfraction stratifiées ensemble. Dans l'espace colorimétrique L*a*b*, ledit film bloquant les IR a une valeur L* qui satisfait à la relation L* < 90, une valeur a* qui satisfait à la relation −10 ≤ a* ≤ 10, et une valeur b* qui satisfait à la relation b* < −4.
