Abstract

The present invention relates to platelet-shaped zinc-magnesium pigments, wherein the platelet-shaped zinc-magnesium pigments comprise the 40.8 to 67.8 mol % of zinc, 32.2 to 59.2 mol % of magnesium and 0 to 7 mol % of Mn, Li, Be, Y, Sn, Al, Ti, Fe, Cu and mixtures thereof, based in each case on the total molar amount of the elements Zn, Mg, Mn, Be, Y, Li, Sn, Al, Ti, Fe and Cu, where the molar percentages add up to 100 mol %, and the median thickness h50 of the pigments is less than 1 μm. The invention further relates to the use and production of these pigments.
