Goniochromatic pigments, process for their manufacture and their use in the production of printing inks

Abstract

Abstract The invention relates to goniochromatic combination pigments comprising metal oxide-coated planar translucent carrier particles onto which a metal coating from the group comprising copper, silver, gold, a platinum-group metal, silicon, chromium, indium, tin, nickel, germanium and aluminium has been deposited. In the preparation of these goniochromatic pigments, the metals are deposited chemically or physically or chemico-physically in an at least partially optically semi-transparent coating onto the metal oxide-coated carrier particles. The goniochromatic pigments obtained in this way are particularly suitable for the production of printing inks.
