Powder coating and method for producing a powder coating
The invention relates to a powder paint comprising at least one base powder paint and at least one effect powder paint having effect pigments, said effect pigments being dispersed in a melt made from transparent effect powder paint. The invention also relates to a method for producing said type of powder paint and to an effect powder coating containing said type of powder paint.
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 67h.sub.1578 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 67h.sub.1578 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
BRIGHT PIGMENT DISPERSION AND METHOD FOR FORMING MULTILAYER COATING FILM
The present invention relates to an effect pigment dispersion comprising water, a flake aluminum pigment, and a cellulose-based rheology control agent, wherein the effect pigment dispersion contains 0.1 to 10 parts by mass of solids based on 100 parts by mass of all components thereof, the viscosity measured using a Brookfield type viscometer is 400 to 10000 mPa.Math.sec at a rotational speed of 6 revolutions per minute, and the solids content of the flake aluminum pigment is 30 to 200 parts by mass based on 100 parts by mass of the total amount of components other than the flake aluminum pigment in the total solids content.
Pigment compositions containing chlorinated copper phthalocyanine pigments in the gamma crystal form
The present technology is directed to pigment compositions having a pure, or substantially pure, crystal form, containing less chlorine than standard tetrachlorinated copper phthalocyanine pigments, while giving similar color space, chromaticity, fastness properties, and color travel in automotive waterborne and solvent borne systems. These pigments are more advantageous from a toxicity and environmental perspective, and allow the manufacturer to produce pigments in a safe and economical manner.

ARTICLE WITH CURVED PATTERNS FORMED OF ALIGNED PIGMENT FLAKES
In a printed article, pigment flakes are magnetically aligned so as to form curved patterns in a plurality of cross-sections normal a continuous imaginary line, wherein radii of the curved patterns increase along the imaginary line from the first point to the second point. When light is incident upon the aligned pigment flakes from a light source, light reflected from the aligned pattern forms a bright image which appears to gradually change its shape and move from one side of the continuous imaginary line to another side of the continuous imaginary line when the substrate is tilted with respect to the light source.
