Ceramic colours containing effect pigments and a liquid glass forming component for decoration of metallic, ceramic and glassy articles and a process for the preparation of a ceramic glaze.

Ceramic colours

Frits or frit mixtures with pearlescent pigments for materials, such as ceramic glazes, which are stable above 1000&#xb0; C.

Pigment/frit mixtures

The present invention relates to pearlescent pigments based on flake-form substrates which have at least one FeOOH layer and at least one TiOlayer or at least one TiO/SiO/TiOlayer package, and to the use thereof, inter alia, in paints, coatings, printing inks, powder coatings, plastics and in particular in care and decorative cosmetics.

Pearlescent pigments

Disclosed are particles containing substrates and an anion-binding layer, containing one or more anion-forming organic active compounds or active compound/colorant mixtures; processes for preparing said particles and to methods of use thereof in cosmetics, pharmaceuticals, formulations, paints, coatings, plastics, films, in security printing, in security features in documents or identity papers, for coloring seed, for coloring foods or in medicament coatings and for the preparation of pigment compositions and dry preparations.

Particles comprising an anion-binding layer containing anion-forming organic active compounds, and method of making and using thereof

Disclosed are a pigment comprising a flake-form substrate, where natural and synthetic clay minerals are excluded as substrate, and an anion-binding layer, in particular comprising a layered double hydroxide, where the anion-binding layer comprises anion-forming organic, inorganic and/or organometallic colorants; and a process for the preparation of said pigment and to the use thereof in cosmetics, paints, coatings, plastics, films, in security printing, in security features in documents and identity cards, for coloring seed, for coloring foods or in medicament coatings, and for the preparation of pigment compositions and dry preparations.
