    Abstract: Disclosed is a composition comprising a charged particle of volume 5 nm3 to 50 million nm3 preferably having an inorganic core of SiO2, AI2O3, and/or TiO2, or a core essentially consisting of an organic pigment and/or pigment derivative, and a counter ion which is separable from the particle and is not covalently linked to the particle, said counter ion comprising a silicon atom which is directly bound to a carbon atom. Preferably, said charged particle comprises a dye attached to said inorganic core and said counter ion comprises a (poly)siloxane moiety linked via suitable bridge members to a quaternary, positively charged, nitrogen or phosphorus atom, or to a moiety carrying an anionic functional group. Said composition may be used e.g. in the form of a homogenous dispersion in an electrophoretic display.

    Abstract: The invention relates to an electrophoretic display, comprising electrodes and cells containing at least one kind of ionic, monochrome particles, a non-polar liquid and a dispersant, wherein the ionic, monochrome particles of at least one kind are essentially aggregates consisting of a carbon containing pigment and a cationic pigment orcationic pigment derivative, and the dispersantis selected from the group consisting of polyacrylates, polyesters, polyurethanes and copolymers, with the proviso that the cationic pigment or cationic pigment derivative is not a reaction product of carbonblack with diazotated procaine hydrochloride. In general, the whole quantity of the pigment and the main part, preferably at least 80%, most preferred from 95% to 100%, of the whole cationic pigment or cationic pigment derivativepresent within the cells is comprised in the aggregates, with essentially no pigment and only a minor part of the cationic pigment or cationic pigment derivative physically distinct from the aggregates.
