Abstract
Official abstract text for this publication.
The present invention relates to intensely colored and/or optically variable pigments which have a flake-form transparent or semitransparent electrically conductive core and at least one coloring dielectric layer surrounding the core, to a process for the preparation of such pigments, and to the use thereof.
First claim
Opening claim text (preview).
The invention claimed is: 1. A pigment powder comprising a pigment comprising a flake-form transparent or semitransparent electrically conductive core and at least one coloring dielectric layer surrounding the electrically conductive core, wherein the electrically conductive core has a transparent or semitransparent flake-form substrate and a coating located on all or both sides of the substrate, where the coating has a single- or multilayered structure and at least the outer layer…
