The invention relates to powder made of coated PVD metal effect pigment, highly concentrated suspensions of coated PVD metal effect pigment as well as the use thereof in powder lacquers and masterbatches. The powder according to the invention made of coated PVD metal effect pigments is characterized by a very good redispersibility and is outstandingly suitable in particular for the preparation of highly concentrated suspensions. Furthermore, it is very free flowing, substantially agglomerate-free and results in coatings with excellent metallic gloss.

The present invention is related to effect pigments exhibiting a deep black body color as well as a blue interference color, to a process for the production of such pigments as well as to the use thereof, especially in coating compositions.

Disclosed is a composite white pigment having mixed together white pigments having different colorimeter values from each other by comprising substrates having various sizes and/or TiO2 having various thicknesses. The composite white pigment, according to the present invention, comprises: a first white pigment comprising a substrate and a white metal oxide layer formed on the substrate; and a second white pigment comprising a substrate and a white metal oxide layer formed on the substrate, and having a different colorimeter value from that of the first white pigment.

The present invention relates to laser-markable polymers and coatings which are distinguished by the fact that they comprise tin/antimony oxide-coated spherical TiO.sub.2 particles of defined particle size as laser additive.
