Title
(EN) THIN FILM INTERFERENCE PIGMENTS WITH NANOPARTICLES COATING
(FR) PIGMENTS D'INTERFÉRENCE À COUCHES MINCES AVEC REVÊTEMENT DE NANOPARTICULES
Abstract
(EN)
An article including a thin film interference pigment; and a coating including a selectively absorbing nanoparticle is disclosed. The article can exhibit increased chromaticity as compared to the thin film interference pigment alone. Methods of making the article are also disclosed.
(FR)
Cette invention concerne un article comprenant un pigment d'interférence à couches minces ; et un revêtement comprenant une nanoparticule à absorption sélective. L'article peut présenter une chromaticité accrue par rapport au seul pigment d'interférence à couches minces. L'invention concerne en outre des procédés de fabrication de l'article.
