The present invention relates to aluminium effect pigments having the following properties: na) a d 50 -value of the volume averaged particle size distribution curve of 1 µm to 15 µm, nb) an average thickness h 50 of 15 to 150 nm determined by counting from SEM images, nc) 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 invention 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. |
