The present invention relates to non-metallic interference pigments, in particular laminar interference pigments, which comprise a thin high-refractive layer and an outermost layer that contains crystalline carbon in the form of graphite and/or graphene. The invention also relates to a method for producing such pigments and the use of the thus produced pigments.

The present invention relates to electrically conductive, coloured interference pigments, in particular flake-form interference pigments, which have an outermost layer which comprises crystalline carbon in the form of graphite and/or graphene, to a process for the preparation of such pigments, and to the use of the pigments prepared in this way.

The present invention provides a glitter pigment, including: a glass flake; a titanium oxide layer formed over the glass flake; and fine gold particles deposited on the titanium oxide layer, wherein the fine gold particles include fine gold particles P2 having a particle diameter of 20 nm or more and less than 50 nm, and in a square region 2 μm on a side on a surface of the titanium oxide layer on which the fine gold particles are deposited, the number of the fine gold particles P2 is 9 or more and less than 100 and an average of distances between the fine gold particles P2 is 130 nm or more and less than 500 nm, each of the distances being a distance from one of the fine gold particles P2 to another fine gold particle P2 nearest to the one.

The present invention is related to effect pigments exhibiting a deep black body color as well as a blue interference color, to a process for the production of such pigments as well as to the use thereof, especially in coating compositions.

The present invention relates to semitransparent pearlescent pigments, to processes for producing them, and to the use of such pearlescent pigments, where the pearlescent pigments comprise monolithically constructed substrate platelets composed of a metal oxide having an average thickness of 1 to 40 nm and a form factor, expressed by the ratio of the mean size to the average thickness, of at least 80, which are enveloped by at least one substantially transparent coating A composed of at least one low-index metal oxide and/or metal oxide hydrate, having a refractive index of less than 1.8, and at least one interference layer in the form of a coating B composed of at least one high-index metal oxide, having a refractive index of at least 1.8.

An article including a reflector having a first surface and a second surface opposite the first surface; a first selective light modulator layer external to the first surface of the reflector; a second selective light modulator layer external to the second surface of the reflector; a first absorber layer external to the first selective light modulator layer; and a second absorber layer external to the second selective light modulator layer; wherein each of the first and second selective light modulator layers include a host material is disclosed herein. Methods of making the article are also disclosed.

The present invention relates to effect pigments which are based on flake-form substrates having a circular form factor of 1.2-2 and are coated with at least one high-refractive-index layer, and to the use thereof, inter alia in paints, coatings, printing inks, plastics and in cosmetic formulations.

A pearlescent pigment for security purposes according to an embodiment of the present invention includes a single or a plurality of coating layers containing a metal oxide and an organic or inorganic fluorescent material. Since the pearlescent pigment for security purposes according to the present disclosure includes a fluorescent layer containing the organic or inorganic fluorescent material, it can be used as a pigment for security purposes due to its optical characteristics and can also provide effects such as magnetism, high color intensity, multiple colors, etc. Also, since the pearlescent pigment for security purposes has aesthetic benefit and security characteristic at the same time, it is economical, easy to use and applicable in various industries.

Temperature-stable effect pigments based on multicoated flake-form substrates, and the use thereof in paints, coatings, printing inks, plastics and in particular in glazes, enamels, ceramic or glass-like materials.

An article including a reflector having a first surface and a second surface opposite the first surface; a first selective light modulator layer external to the first surface of the reflector; a second selective light modulator layer external to the second surface of the reflector; a first absorber layer external to the first selective light modulator layer; and a second absorber layer external to the second selective light modulator layer; wherein each of the first and second selective light modulator layers include a host material is disclosed herein. Methods of making the article are also disclosed.
