Title
(DE) MEHRSCHICHTIGES PERLGLANZPIGMENT
(EN) MULTILAYER NACREOUS PIGMENT
(FR) PIGMENT A LUSTRE NACRE MULTICOUCHE
Abstract
(DE)
Mehrschichtiges Perlglanzpigment auf Basis eines plättchenförmigen Substrates aus einem Material mit niedriger Brechzahl im Bereich von 1,35 bis 1,8, das mindestens (i) eine erste Schicht aus einem Material mit einer Brechzahl von grösser als 1,8, (ii) wahlweise eine zweite Schicht aus einem Material mit niedriger Brechzahl im Bereich von 1,35 bis 1,8, (iii) eine semitransparente Metallschicht, die auf dem Substrat oder den Schichten (i) oder (ii) aufgebracht ist und (iv) gegebenenfalls eine Nachbeschichtung aufweist, wobei das Substrat plättchenförmiges Siliciumdioxid, Aluminiumoxid, Boroxid oder Magnesiumfluorid ist.
(EN)
The invention relates to a multilayer nacreous pigment which is based on a lamellar substrate consisting of a material with a low refractive index of between 1.35 and 1.8 and which has at least the following: (i) a first layer consisting of a material with a refractive index of more than 1.8; (ii) optionally, a second layer consisting of a material with a low refractive index of between 1.35 and 1.8; (iii) a semi-transparent metal layer which is applied to the substrate or to the layers (i) or (ii); and (iv) optionally, a re-coating; the substrate being lamellar silicon dioxide, aluminium oxide, boron oxide or magnesium fluoride.
(FR)
L'invention concerne un pigment à lustre nacré multicouche, à base d'un substrat en paillettes, réalisé avec un matériau dont le faible indice de réfraction se situe entre 1,35 et 1,8. Ledit pigment présente au moins (i) une première couche, réalisée avec un matériau dont l'indice de réfraction est supérieur à 1,8, (ii) facultativement, une seconde couche, réalisée avec un matériau dont le faible indice de réfraction se situe entre 1,35 et 1,8, (iii) une couche métallique semi-transparente, disposée sur le substrat ou sur les couches (i) ou (ii), et (iv) éventuellement une surcouche. Le substrat est composé de paillettes de dioxyde de silicium, d'oxyde d'aluminium, d'oxyde de bore ou de fluorure de magnésium.
