Titanium phosphate powder, production method therefor, and white pigment for cosmetics

The titanium phosphate powder of the present invention includes plate-shaped crystalline particles of titanium phosphate, an average thickness of the plate-shaped crystalline particles is 0.01 μm or more and less than 0.10 μm, and an aspect ratio, which is a value obtained by dividing an average primary particle diameter of the plate-shaped crystalline particles by the average thickness, is 5 or more. In the method for producing a titanium phosphate powder of the present invention, a raw material containing titanium and phosphorus is caused to react by a hydrothermal synthesis method, and when the titanium phosphate powder including plate-shaped crystalline particles of titanium phosphate is produced, a mixture of titanium sulfate and phosphoric acid is used as the raw material.

Effect pigments based on artificially produced substrates with a narrow size distribution

The invention relates to effect pigments comprising artificial platelet-shaped substrates which have at least one optically active coating, where the effect pigments have a volume-averaged cumulative undersize distribution curve with the characteristic numbers D.sub.10, D.sub.50 and D.sub.90, said cumulative undersize distribution curve having a span ΔD of 0.7-1.4, and the span ΔD being calculated in accordance with formula (I):
ΔD=(D.sub.90−D.sub.10)/D.sub.50  (I),
and the average thickness of the artificial platelet-shaped substrates being 500 nm to 2000 nm.

Golden effect pigments

A golden effect pigment comprising an optionally passivated platelet-shaped metallic substrate and an iron oxide layer, wherein the effect pigment has a hue angle h.sub.15 of 67°≤h.sub.15≤78° and a chroma C*.sub.15 of ≥90 is provided. Further, a golden effect pigment comprising an optionally passivated platelet-shaped metallic substrate and an iron oxide layer, wherein the effect pigment has a hue angle h.sub.15 of 67°≤h.sub.15≤78° and a chroma C*.sub.45 of ≥50 is provided. The golden effect pigments are highly chromatic and suitable for coloring a coating composition such as a paint, a printing ink, an ink, a varnish, plastics, a fiber, a film or a cosmetic preparation, preferably an automotive, an architectural or an industrial coating composition.
