  • Highly lustrous silver-colored pigments with high opacity and metallic appearance, process for the preparation thereof and use of same
    Patent number: 9265701
    Abstract: A silver-colored pigment is provided having a nonmetallic platelet-shaped substrate and at least one ilmenite-containing coating, wherein the nonmetallic platelet-shaped substrate is a nonmetallic platelet-shaped synthetic substrate and the amount of iron compounds, calculated as elemental iron, in the pigment is less than 5.0 % by weight, based on the total weight of the pigment. Processes for preparing the pigment also are provided.
    Type: Grant

  • PIGMENT MIXTURE OF PVD ALUMINIUM EFFECT PIGMENTS AND THIN ALUMINIUM EFFECT PIGMENTS FROM MILLING, PROCESS FOR PREPARATION THEREOF AND USE THEREOF
    Publication number: 20110083582
    Abstract: 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 H50,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 h50,conv. value in a range from 15 nm to 100 nm, and c) 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.
