摘要:
The invention relates to multilayered interference pigments which comprise a platelet-shaped substrate of silicon dioxide which is coated alternately with layers of light-transparent materials having refractive indices of n>1.8 and layers of light-transparent materials having refractive indices of n≦1.8, where the optical thickness of the platelet-shaped substrate and the optical thickness of the individual layers of light-transparent materials having refractive indices of n≦1.8 are the same.
摘要:
The present invention relates to multilayered interference pigments comprising a platelet-shaped substrate which is coated with alternating layers of materials of high and low refractive index, where the total thickness of the interference pigments is not greater than 1 μm. The present invention likewise relates to processes for the preparation of these pigments, in which a substrate is coated alternately with layers of materials of high and low refractive index, where the thicknesses of the layers of materials of high and low refractive index are selected in such a way that the total thickness of the interference pigments does not become greater than 1 μm, and to the use of these pigments in cosmetics, paints, coatings, plastics, films, in security printing, in security features in documents and identity cards, for coloring seed, for coloring foods or in medicament coatings, and for the preparation of pigment compositions and dry preparations.
摘要:
The invention relates to flake-form effect pigments, characterised in that they consist of transparent or semitransparent materials and have a groove or grid structure, to processes for the production thereof, and to the use thereof.
