Title
(EN) COMPOSITE MATERIAL HAVING IMPROVED AESTHETICS AND COLOR AFTER SECONDARY OPERATIONS
(FR) MATÉRIAU COMPOSITE PRÉSENTANT UN ASPECT ESTHÉTIQUE ET UNE COULEUR AMÉLIORÉS APRÈS DES OPÉRATIONS SECONDAIRES
Abstract
(EN)
A composite material includes: a substrate layer; a first layer including a thermoplastic material applied to the substrate layer, the first layer having a refractive index greater than 1.2 resulting from application of at least one secondary process to the first layer; and a surface coating including a transparent polymer applied to the first layer. The surface coating has a refractive index of from 1 to 2. Methods for making the composite material and articles including the composite material are also described.
(FR)
L'invention concerne un matériau composite comprenant : une couche de substrat ; une première couche comprenant un matériau thermoplastique appliqué à la couche de substrat, la première couche présentant un indice de réfraction supérieur à 1,2 résultant de l'application d'au moins un procédé secondaire à la première couche ; et un revêtement de surface comprenant un polymère transparent appliqué à la première couche. Le revêtement de surface présente un indice de réfraction de 1 à 2. L'invention concerne également des procédés de préparation du matériau composite et des articles comprenant le matériau composite.
