Abstract:
Iridescent magnetic pigments are produced by depositing a ferrite layer and a second metal oxide layer in succession on a substrate. The substrate may be platy and is coated with the ferrite, which is then coated with the second metal oxide layer to provide interference color effect. At least one of the layers is magnetic. The magnetic pigment may be used in coatings such as paints.
