Abstract: The invention relates to the production of mixed-metal-oxide inorganic pigments, using industrial waste as raw materials, comprising the following steps: (i) characterization and selection of wastes; (ii) their treatment, if required; (iii) formulation + dosing + mixing of components; (iv) drying + calcination; and (v) washing + milling. Selected wastes might be used in the as- received condition or after drying or calcination. The present invention deals with materials that are produced by colorants or pigments producers mainly for use in the ceramic sector, since formulations are stable at high temperatures and act as colorants of glazes or ceramic bodies. The use of high temperatures might also assure the desirable inertization of possible hazardous species.

Abstract: In electrophoretic media, it is advantageous to use pigment particles having 1 to 15 per cent by weight of a polymer chemically bonded to, or cross-linked around, the pigment particles. The polymer desirably has a branched chain structure with side chains extending from a main chain. Charged or chargeable groups can be incorporated into the polymer or can be bonded to the particles separately from the polymer. The polymer-coated particles can be prepared by first attaching a polymerizable or polymerization-initiating group to the particle and then reacting the particle with one or more polymerizable monomers or oligomers.
