Title (EN) INTERFERENCE PIGMENTS
(FR) PIGMENTS D’INTERFÉRENCE
Abstract:
(EN) The present invention relates to interference pigments based on platelet- shaped substrates which are coated with at least four high refractive layers and to the use thereof, inter alia in paints, coatings, printings inks, plastics and in particular in cosmetic formulations. The interference pigments show a moderate chroma and can be used as effect pigments, as filler pigments and as protection agent against near infrared radiation, VIS and high energy light.
(FR) La présente invention concerne des pigments d’interférence à base de substrats en forme de plaquettes qui sont revêtus d’au moins quatre couches de réfraction élevée et leur utilisation, entre autres dans les peintures, les revêtements, les encres d’impression, les plastiques et en particulier les formulations cosmétiques. Les pigments d’interférence présentent une saturation modérée et peuvent être utilisés comme pigments à effet, comme pigments de charge et comme agent de protection contre le rayonnement proche infrarouge, la lumière visible et de haute énergie.
