Abstract: The present invention relates to the use of a modified effect pigment in a radiation-curable coating composition, wherein the modified effect pigment is an effect pigment that is coated with at least one metal oxide layer to which at least one organic compound having one or more functional groups with a carbon-carbon multiple bond is bound. The invention is particularly suitable for metallic effect pigments, in particular aluminum pigments. A further part of the invention is the use of a modified effect pigment in a radiation-curable coating composition, wherein the modified effect pigment is an effect pigment to which at least one organic compound having one or more functional groups with a carbon-carbon multiple bond is bound. The radiation-curable, preferably UV-curable, coating compositions can in particular be lacquers, paints, printing inks, nail varnish or plastics.

Abstract: 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.

Abstract: The invention relates to surface-modified metal effect pigments, which are covered are with a metal oxide layer, wherein a silane layer which has at least two different bifunctional silanes is bonded to this layer. The invention is particularly suitable for metal effect pigments of aluminium, titanium, zirconium, copper, zinc, gold, silver, tin, steel and iron, in particular aluminium pigments. In addition the invention also relates to a process for the production of the surface-modified metal effect pigments and use thereof in water-based, solvent-based or radiation-curing coating compositions.
