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.

Carbon black in effect pigments

This invention is directed to a method of modifying the refractive index of multilayer thin films structure comprising high refractive and low refractive index layers, where the high refractive and low refractive index layers are of the same material, the method comprises a) depositing a first layer of film of a refractive index on a substrate; b) depositing a second layer of film having a different refractive index onto the first layer of film; and c) depositing a third layer of film having a different refractive index from the second layer of film onto the second layer of film, and compositions thereof. In certain embodiments, this multilayer thin film structure of this invention is directed to decorative applications.

Method of making thin film structures and compositions thereof

A multilayer effect pigment includes a transparent substrate, a layer of high refractive index material on the substrate, and alternating layers of low refractive index and high refractive index materials on the first layer, the total number of layers being an odd number of at least three, all adjacent layers differing in refractive index by at least about 0.2 and at least one of the layers having an optical thickness which is different from all of the other layers. The resulting multilayer effect pigment is not a quarter-wave stack. The present effect pigments may be used in cosmetic and industrial applications.

Transparent goniochromatic multilayer effect pigment

A color effect material is described as composed of a plurality of encapsulated substrate platelets in which each platelet is encapsulated with a highly reflective layer which acts as a reflector to light directed thereon and a spacer pigment layer which is selectively transparent to light directed thereon.

Multi-layer effect pigment

A multilayer effect pigment includes a transparent substrate, a layer of high refractive index material on the substrate, and alternating layers of low refractive index and high refractive index materials on the first layer, the total number of layers being an odd number of at least three, all adjacent layers differing in refractive index by at least about 0.2 and at least one of the layers having an optical thickness which is different from all of the other layers. The resulting multilayer effect pigment is not a quarter-wave stack. The present multilayer effect pigment may be used in cosmetics or personal care products.

Multilayer effect pigment

The present invention relates to a complex inorganic color effect pigment material based on multiply coated platelet-shaped substrates wherein one of the layers is a complex inorganic colored pigment. The present color effect pigment may be used in automotive applications, security inks, and decorative coatings.

Complex inorganic effect materials

An effect pigment is constituted by coated laminar platelets in which the platelets are a mixture of different platelet materials, one of which is platy glass or platy aluminum oxide, and in which the pigment exhibits visual homogeneity.
