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

摘要

A mixture of aluminum effect pigments, the mixture comprising:a) PVD aluminum effect pigments (PVD Al) which, in a thickness distribution as determined via thickness counting by scanning electron microscopy (SEM) and represented as cumulative frequency distribution, have an H_50,PVD value in a range from 10 nm to 7 nm,b) aluminum effect pigments (conv.-Al) which have been produced by milling methods and, in a thickness distribution as determined via thickness counting by scanning electron microscopy (SEM) and represented as cumulative frequency distribution, have an h_50,conv. value in a range from 15 nm to 100 nm, andc) a 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 disclosure further relates to a process for preparing the mixture and to the use of the mixture.
