摘要:
Multilayer interference pigments consisting of a transparent carrier material coated with alternating layers of metal oxides of low and high refractive index, the layers of the metal oxides of low refractive index being optically inactive.The thickness of the metal oxide layers of high refractive index is an integral multiple of the optical thickness which is necessary for the desired interference color.The layer thickness of metal oxide layers of low refractive index is from 1 to 20 nm.
