FIELD: chemistry.

SUBSTANCE: invention relates to compositions, containing specifically functionalised charged particles and counterions, applied in electrophoresis, for instance in electrophoresis displays. Composition for electrophoresis displays contains charged particle with volume from 5 nm³ to 50 million nm³, preferably having inorganic core of SiO₂, Al₂O₃ and/or TiO₂, or mixed SiO₂, Al₂O₃ and/or TiO₂ core, or core, mainly consisting of organic pigment and/or pigment derivative and counterion, separated from particle and not connected with particle covalently, with said counterion containing polysiloxane, containing silicon atom, which is directly bound with carbon atom.

EFFECT: invention makes it possible to obtain composition, containing coloured charged particles, suitable for energy effective electrophoresis displays.
