Mica coated with metal oxide as a flame retardant

Carbon dioxide sorbents for indoor air quality control

The use of an effect pigment (a) comprising an aluminum-based substrate and an iron oxide coating having a red 1order interference color in combination with a colored absorption pigment (b) for producing a coating having enhanced coloristic properties, in particular enhanced chroma, lightness and hiding power, is provided. The pigment combination of (a) and (b) is suitable for coloring plastics, a fiber, a film and a coating composition such as a paint, a printing ink, a varnish or a powder coating, preferably an automotive, an architectural or an industrial coating composition.

Use of iron oxide coated aluminum flakes having red 1order interference color in coatings

The present invention relates to a coloured effect pigment, comprising a substrate made of aluminium or an aluminium alloy which is optionally coated with one or more passivation layers, and an aluminium-doped iron oxide layer.

Non-magnetizable effect pigments

An iron oxide containing effect pigment, and methods for producing and using the same are discussed. The iron oxide containing effect pigment may include an iron oxide coating in direct contact with a particulate substrate, which may have high levels of hematite, magnetite, or maghemite; and low amounts of toxic metals. A method for producing the pigment may include chemical vapor deposition of iron pentacarbonyl onto a particulate substrate. The iron oxide containing effect pigments may be incorporated into compositions, such as cosmetics.

Iron oxide containing effect pigments, their manufacture and their use

A bismuth vanadate pigment is provided which pigment is doped with a combination of Mg, Al and P and optionally an element E, wherein the molar ratios of the Bi, V, Mg, Al, P and E correspond to a formulaBi MgAlEVPO&#x2003;&#x2003;(I)wherein E is selected from the group consisting of Be, Ca, Sr, Ba, Zr, Mo, Ce and a combination thereof; 0.001&#x2266;a&#x2266;0.2; 0.001&#x2266;b&#x2266;0.2; 0&#x2266;c&#x2266;1.7; 0.5&#x2266;d&#x2266;2.3; 0.001&#x2266;e&#x2266;0.5; and f denotes the number of oxygen atoms for satisfying the valence requirements of the cations. The pigment may be used as colorant in various applications, especially in coloring high molecular weight organic material, for example, coating compositions, paints, printing inks, liquid inks, plastics, films, fibers, or glazes for ceramics or glass.

Bismuth vanadate pigments

The present invention relates to a process for preparing a colored effect pigment, comprising: (i) coating aluminum-based substrate particles in an aqueous coating medium with at least one metal oxide layer, wherein the metal oxide is selected from a titanium oxide, an iron oxide, or any mixture thereof, (ii) providing a mixture of the coated aluminum-based substrate particles and a particulate inorganic non-metallic material in the aqueous coating medium by adding the particulate inorganic non-metallic material to the aqueous coating medium, and (iii) separating the mixture of the coated aluminum-based substrate particles and the particulate inorganic non-metallic material from the aqueous coating medium and subjecting the separated mixture to a thermal drying step so as to obtain a dry colored effect pigment material.

Process for preparing metal oxide coated aluminium effect pigments

The present invention relates to a process for preparing a coloured effect pigment, comprising the steps of (a) preparing in an aqueous coating medium at least one layer of a hydroxyl-containing metal oxide on a substrate, thereby obtaining in the aqueous coating medium a first coloured pigment material CPM1 comprising the substrate coated with the hydroxyl-containing metal oxide, wherein the substrate is made of aluminium or aluminium alloy which optionally comprises at least one passivating layer, and wherein the hydroxyl-containing metal oxide is a hydroxyl-containing iron oxide or a hydroxyl-containing titanium oxide or a mixture thereof, (b) providing the first coloured pigment material CPM1 in a liquid post-treatment medium comprising one or more high boiling organic liquids, and (c) heating the liquid post-treatment medium to a temperature of at least 90&#xb0; C. so as to convert the first coloured pigment material CPM1 to a second coloured pigment material CPM2.

Process for preparing an effect pigment

An inorganic red pigment is provided which pigment comprises titanium oxide, tin oxide, zinc oxide, and tungsten oxide, wherein the molar ratios of the oxides correspond to a composition of formula(TiO)(SnO)(ZnO)(WO)&#x2003;&#x2003;(I), whereinSnOcomprises SnO and SnOin a molar ratio of SnO:SnOof from 70:30 to 100:0; 0.8&#x2266;a&#x2266;3.0; 0.3&#x2266;b&#x2266;2.0; 0.3&#x2266;c&#x2266;1.3; and 0.01&#x2266;d&#x2266;0.8. Optionally, SiO, other metal oxides or metal sulfides may be present. The inorganic pigment may be used as colorant in various applications.

Inorganic red pigment

Described are thin plane-parallel aluminum flakes illustrated in FIG.having a thickness of up to 200 nm and comprising an inner layer of oxidized aluminium having a thickness of 0.5-30 nm, a process for the manufacture thereof and the use thereof, e.g. in formulations, like paints, electrostatic coatings, printing inks, plastics materials, and cosmetics. Surprisingly, due to the inner layer of oxidized aluminum the aluminum flakes have an improved shear stability as evidenced e.g. by the difference in lightness before and after shear stress.
