  • INK JETPRINTING INK CONTAINING THIN ALUMINIUM EFFECT PIGMENTS AND METHOD
    Publication number: 20120274714
    Abstract: Aluminium effect pigments having the following properties: a) a d50-value of the volume averaged particle size distribution curve of 1 ?m to 15 ?m, b) an average thickness h50 of 15 to 150 nm determined by counting from SEM images, c) an x-ray diffractogram measured on said aluminium effect pigments in essentially plane-parallel alignment showing main peaks which are not [111]- or [222]-reflections. Furthermore, the disclosure relates to an ink jet printing ink and a method of producing an ink jet printing ink and the use of aluminium effect pigments as well as an ink jet printing ink.
