摘要
The invention relates to semitransparent pearlescent pigments, to methods for producing same, and to the use of such pearlescent pigments, wherein the pearlescent pigments are monolithically constructed substrate platelets composed of a metal oxide having an average thickness of 1 to 40 nm and a form factor, expressed by the ratio of the average size to the average thickness, of at least 80, which are encased by at least one substantially transparent coating A composed of at least one low-refractive-index metal oxide and/or metal oxide hydrate, which has a refractive index of less than 1.8, and comprise at least one interference layer in the form of a coating B composed of at least one high-refractive-index metal oxide, which has a refractive index of at least 1.8.
