PIGMENT MIXTURE OF PVD ALUMINIUM EFFECT PIGMENTS AND THIN ALUMINIUM EFFECT PIGMENTS FROM MILLING, PROCESS FOR PREPARATION THEREOF AND USE THEREOF

摘要

The invention relates to a mixture of aluminium effect pigments, the mixture comprising a) PVD aluminium effect pigments (PVD‑Al), which for a thickness distribution, as determined via thickness counting by scanning electron microscopy (SEM) and represented as cumulative frequency distribution, have an h50,PVD value from a range from 10 nm to 70 nm, b) aluminium effect pigments (conv.‑Al), which have been produced by milling methods and, for a thickness distribution as determined via thickness counting by scanning electron microscopy (SEM) and represented as cumulative frequency distribution, have an h50,conv value from a range from 15 nm to 100 nm, and c) solvent or solvent mixture, with the proviso that the weight ratio of PVD‑Al to conv.‑Al is 99:1 to 1:99 and the solvent content is at least 30% by weight, based on the total weight of the mixture. The invention further relates to a process for preparing this mixture and to the use of this mixture.
