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.

The present invention relates to colored effect pigments, in particular to those containing an organic color pigment layer, to a preparation method thereof and to the use of these pigments especially in a composition comprising the colored effect pigments.

An aqueous coating composition includes an aluminum pigment, and the aluminum pigment is composed of tabular particles which are surface-treated by a fluorine-containing compound and which have an average thickness (Z) of 8 to 100 nm in a thickness direction thereof.

An inorganic paint pigment may include a fluid matrix, and paint flakes carried within the fluid matrix. Each paint flake may include a common aluminum layer having a first major surface and a second major surface opposing the first major surface, a first plasmonic aluminum reflector layer carried by the first major surface, and a second plasmonic aluminum reflector layer carried by the second major surface.

A method for producing a luster pigment containing a plurality of scaly pigment particles that is capable of suppressing reactions between an aluminum layer as a core layer of each pigment particle and water, even when the luster pigment is exposed to atmosphere containing oxygen or water. The method includes forming a first layer on a surface of a film substrate through deposition of titanium as material, forming a second layer on a surface of the first layer through deposition of aluminum as material, and forming a third layer on a surface of the second layer through deposition of titanium as material, so as to form a stack including the first layer, second layer, and third layer stacked in sequence on the surface of the film substrate, and removing the stack from the film substrate and crushing the removed stack, so as to produce the plurality of scaly pigment particles.

There is disclosed a lamellar particle including an unconverted portion of the lamellar particle, wherein the unconverted portion includes a first metal, a converted portion of the lamellar particle disposed radially outward of at least one of a surface of the unconverted portion, wherein the converted portion includes a chemical compound of the first metal.
