Copper-containing metal pigments with a metal oxide layer and a plastic layer, method for the production thereof, coating agent and coated object

摘要

The invention relates to copper-containing metal pigments, wherein the copper-containing metal pigments have an elemental copper content of at least 50 wt.-%, relative to the total weight of the uncoated copper-containing metal pigment, wherein the copper-containing metal pigments have at least one enveloping metal oxide layer and at least one enveloping chemically non-reactive plastic layer, wherein the sum of the amounts of the at least one chemically non-reactive plastic layer and of the at least one metal oxide layer lies in a range of from 10 to 50 wt.-%, relative to the weight of the uncoated metal pigment, and the weight ratio of the at least one metal oxide layer to the at least one chemically non-reactive plastic layer lies in a range of from 1:2 to 1:20. The invention furthermore relates to a method for producing these pigments and the use thereof.
