摘要：

The invention relates to effect pigments having an aluminum or aluminum alloy core and a aluminum or aluminum alloy core wrapped aluminum oxide or aluminum oxide / hydroxide-containing layer obtainable by wet-chemical oxidation of platelet-shaped aluminum or aluminum-alloy pigments, wherein the content of metallic aluminum in the aluminum or aluminum alloy core is not more than 90 wt .-%, based on the total weight of the pigment, wherein the oxidized aluminum or aluminum-alloy pigments have at least one high-index metal chalcogenide layer having a refractive index of> 1.95, and between the high-index metal chalcogenide layer and the enveloping alumina - or aluminum oxide / hydroxide-containing layer is formed a mixing layer. The invention further relates to a method for producing these effect pigments as well as their use.
