Abstract

Platelet-shaped, copper-containing, metallic effect pigments which have a copper content of 60% to 100% by weight, based on the total metal content, the metal pigments having a thickness distribution as determined via thickness counting by scanning electron microscopy (SEM) and represented as cumulative undersize distribution,
