The present invention relates to pigments, comprising a plate-like substrate of perlite, and (a) a dielectric material, especially a metal oxide, having a high index of refraction; and/or (a) a metal layer, especially a thin semi-transparent metal layer; a process for their production and their use in paints, ink jet printing, for dyeing textiles, for pigmenting coatings (paints), printing inks, plastics, cosmetics, glazes for ceramics and glass.
The present application is directed to combination effect pigments comprising an effect pigment and carbon black, wherein the carbon black is adherently deposited on the effect pigment interposed within the substrate and at least one subsequent layer of the effect pigment. This structure of the combination effect pigment results in advantageous non-staining properties of the pigment and maximizes color effects of the carbon black.
The present application is directed to a combination effect pigment comprising a platy substrate, an outer layer disposed above the platy substrate, and carbon black, wherein the carbon black is disposed above the substrate and is entrapped by the outer layer.
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.

Provided is a treated platy substrate, a method of making it, and methods of using it. The substrate can be synthetic mica, optionally comprising metal-oxide layers. The treated platy substrate is useful in cosmetic compositions.
2 hydrates onto the substrate improves the adhesion and prepares the substrate surface for deposition of the iron oxides onto the platy surface, especially mica surfaces. While the pigment may be used in such applications as coating, powder coating, printing ink, plastic, ceramic material, glass, cosmetic formulation, laser marking pigment, pigment composition or dry preparation, the pigment is especially suitable for cosmetic applications.

Solid, low dust pigment compositions are formed i by mixing pigments with certain polymer stabilizers under conditions wherein the stabilizers are in a liquefied state. The pigment compositions are easily handled and have a high color yield when incorporated into polymer substrates. In many cases, the color development attained is not readily achievable using pigment compositions comprising conventional carriers.
Iridescent magnetic pigments are produced by depositing a ferrite layer and a second metal oxide layer in succession on a substrate. The substrate may be platy and is coated with the ferrite, which is then coated with the second metal oxide layer to provide interference color effect. At least one of the layers is magnetic. The magnetic pigment may be used in coatings such as paints.
