Multilayer pigment based on metal pigment flakes, used e.g. in paint, lacquer, printing ink, security printing ink, plastics, ceramics or cosmetics is produced by exclusively wet chemical coating process

摘要

Multilayer pigments based on metal pigment flakes are produced by exclusively wet chemical coating of the flakes in a one-pot process, in which the pigment is suspended in water and coated first with an amorphous glassy layer at pH 6-11 and then with (mixed) metal oxide(s) at pH less than 4.
