| titleOfInvention | Optically variable pigments having an asymmetrical layer structure |
| abstract | The present invention relates to pigments whose particles have a length of from 2 ~m to 5mm, a width of from 2~m to 2mm and a thickness of from 50 nm t o 1.5~m and a ratio of length to thickness of at least 2:1, the particles havi ng a core of a metallically reflecting material having two substantially parall el faces, the distance between which is the shortest axis of the core, comprisi ng (a), optionally, on one parallel face of the core, an SiOy layer wherein 0.9 5 < y <= 2.0, (b), on the SiOy layer, an SiOx layer wherein 0.03 < x <= 0.95, and (c), on the SiOx layer, an SiOz layer wherein 0.95 < z <= 2.0, to a method for the production thereof, and to the use thereof in paints, textiles, ink- jet printing, cosmetics, coating compositions, plastics, printing inks and i n glazes for ceramics and glass. The pigments without an SiOy layer produce brilliant colours. The pigments with an SiOy layer are opaque and exhibit brilliant colours with a metallic appearance. |
