Title (EN) INTENSELY COLOURED INTERFERENCE PIGMENTS
(FR) PIGMENTS DE POLARISATION A TEINTES DE FORTE INTENSITE
(DE) FARBSTARKE INTERFERENZPIGMENTE
Abstract:
(EN) The invention relates to intensely coloured interference pigments based on multi-layered plate-like substrates with at least two sequences of layers consisting of (A) a colourless layer with a refraction index n $m(F) 1,8; (B) a high-index layer consisting of a mixture of TiO2 and Fe2O3 in a ratio of 1:0.1 to 1:5 and optionally, one or more metal oxides in quantities of $m(F) 20 wt. % in relation to layer (B); and optionally (C) an outer protective layer.
(FR) L'invention concerne des pigments de polarisation à teintes de forte intensité, à base de substrats sous forme de plaquettes à revêtement multicouche, qui présentent au moins deux séquences de couches comprenant : (A) un revêtement incolore à indice de réfraction n $m(F) 1,8 ; (B) un revêtement à indice de réfraction élevé, comprenant un mélange de TiO2 et de Fe2O3, dans un rapport de 1:0,1 à 1:5 et éventuellement un ou plusieurs oxydes métalliques, dans des quantités $m(F) 20 % en poids, par rapport à la couche (B) et éventuellement (C) une couche de protection extérieure.
(DE) Farbstarke Interferenzpigmente auf der Basis von mehrfach beschichteten plättchenförmigen Substraten, die mindestens zwei Schichtenfolgen aus (A) einer farblosen Beschichtung mit einem Brechungsindex n $m(F) 1,8, (B) einer hochbrechenden Beschichtung bestehend aus einem Gemisch aus TiO2 und Fe2O3 im Verhältnis 1:0,1 bis 1:5 und optional ein oder mehreren Metalloxiden in Mengen von $m(F) 20 Gew.% bezogen auf die Schicht (B), und optional (C) einer äusseren Schutzschicht aufweisen.
