The present invention provides a glitter pigment capable of simultaneously achieving electromagnetic wave transmission properties, a high reflectance in appearance, and a neutral color in appearance. The glitter pigment according to the present invention includes: a glass flake 1; and a titanium oxide layer 2 and a silver layer 3 formed in this order on the glass flake 1, wherein a product of the optical thickness of the glass flake 1 and the optical thickness of the titanium oxide layer 2 is 61000 or more and 66000 or less when the optical thickness is expressed in nm, and the silver layer 3 has a physical thickness of 35 nm or more and 55 nm or less.

The present invention relates to a pigment mixture based on spherical particles having a defined particle-size distribution, and to the use thereof in paints, coatings, printing inks, security printing inks, plastics, ceramic materials, glasses, in cosmetic formulations, as tracer, as filler and for the preparation of pigment preparations and dry preparations.

The invention relates to a surface-modified effect pigment comprising particular additives and to the production thereof. The present invention further provides a nail varnish composition comprising a) at least one effect pigment that has been surface-modified with a starting material (additive), where the effect pigment comprises a substrate in platelet form and optionally at least one coating applied to the substrate, b) at least one hydrocarbon resin as binder, and c) at least one solvent or solvent mixture, where the starting material (additive) for surface modification of the effect pigment is at least one compound taken from the group consisting of phosphoric ester-containing, phosphonic ester-containing, phosphonic acid-containing, fatty acid-containing and/or silane-containing compounds or mixtures thereof.

High chroma glitter pigments combine large particle interference pigments and absorption colorants to bring about a unique look. Unlike traditional glitter pigments, the high chroma glitter pigment does not exploit metallic coatings to achieve the sparkle effect. These high chroma glitter pigments produce optical effects and coloration without the need for incorporating additional pigments which, in turn, is a benefit from both a formulation and cost standpoint. In addition to a sparkle effect, the present invention provides high chroma over both dark and light backgrounds, which has been thus far unrealized in prior art. Materials used in the present invention are ethically sourced, environmentally friendly, free of plastic, free of heavy metals, and regulated for cosmetic applications.

The present invention relates to pigments, comprising a plate-like substrate of glass having an average thickness of <1 μm, especially of from 20 nm to 400 nm, and (a) a dielectric material, especially a metal oxide, having a high index of refraction; 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 invention provides a new glitter pigment suitable for providing high-brightness whitish reflected light. The glitter pigment according to the present invention includes: a flaky substrate 1; and a silicon oxide layer 2 and a titanium oxide layer 3 formed in this order on the flaky substrate 1, wherein in the case where the flaky substrate is the glass flake, the glass flake has a thickness of 284 to 322 nm, the silicon oxide layer has a thickness of 89 to 109 nm, and the titanium oxide layer has a thickness of 51 to 86 nm. In the case where the flaky substrate is the alumina flake, the alumina flake has a thickness of 260 to 280 nm, the silicon oxide layer has a thickness of 79 to 102 nm, and the titanium oxide layer has a thickness of 47 to 87 nm.

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 invention relates to compositions based on aromatic polycarbonate which comprise metal oxide-coated micas as effect pigments and exhibit no significant molecular weight degradation of the polycarbonate, apparent from the MVR, under thermal stress. This is achieved by addition of small amounts of an epoxy-containing copolymer or terpolymer of styrene and acrylic acid and/or methacrylic acid in combination with a phosphite-containing thermal stabilizer.

Disclosed is a composite white pigment having mixed together white pigments having different colorimeter values from each other by comprising substrates having various sizes and/or TiO2 having various thicknesses. The composite white pigment, according to the present invention, comprises: a first white pigment comprising a substrate and a white metal oxide layer formed on the substrate; and a second white pigment comprising a substrate and a white metal oxide layer formed on the substrate, and having a different colorimeter value from that of the first white pigment.

A silicate-coated body contains: a mica particle; a first silicate coating at least part of the mica particle; and a functional substance that is carried by the first silicate.
