Filler pigments based on platelet-shaped substrates, which are coated with barium sulfate and at least two metal oxides and/or metal hydroxides are highly suitable as filler pigments especially for cosmetic formulations.

Metal effect pigments, having a surface treatment comprising A) phosphoric acid (H3PO4), B) tetraethyl orthosilicate (TEOS) and C) at least one organic coupling agent to the metal effect pigments, exhibiting excellent humidity resistance performance without any influence on the chroma, luster and color of base metal effect pigments, a process for producing same and their use.

Non-conductive pigments, coatings, films, articles, methods of manufacture thereof, and methods of use thereof are provided. The non-conductive pigment comprises a flake comprising at least four layers comprising alternating low index of refraction layers and high index of refraction layers. A difference in an average index of refraction between adjacent layers as measured over a wavelength range of 400 nm to 700 nm is at least 1.5. In certain examples, the high index of refraction layers have a Q value of at least 0.930, such as, at least 0.950 or at least 1.000. The pigment has an average visible specular reflectance of at least 80% and the pigment exhibits and the flake has a bandwidth of at least 300 nm between an upper wavelength and a lower wavelength at which a specular reflectance drops below 50%.
