摘要:
Goniochromatic luster pigments are based on titanium dioxide-coated silicatic platelets which have been heated in a reducing atmosphere and which comprise at least one layer packet comprising A) a colorless coating having a refractive index n≦1.8 and B) a coating which has a refractive index n≧2.0, which includes iron(III) oxide and which selectively absorbs visible light.
摘要:
Goniochromatic luster pigments comprising at least one dielectric low-refractive interference-colored layer which includes a polar organic solvent which can interact with the layer material via functional groups.
摘要:
The iron oxide platelets comprise at least one layer packet comprising A) a colorless coating having a refractive index n≦1.8, and B) a colorless coating having a refractive index n≧2.0.
