    摘要： 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.

    摘要： The instant invention pertains to a concentrated aqueous dispersion of organic light stabilizers with a particle size of less than 1000 nm, prepared by heterophase radical polymerization of ethylenically unsaturated monomers in the presence of the light stabilizers, wherein the weight ratio of light stabilizer to polymeric carrier is greater than 50/100. Another aspect of the invention is a process for the preparation of such aqueous dispersions with high light stabilizer content. Aqueous dispersions prepared according to this process are useful ingredients for adhesives, aqueous emulsions of natural or synthetic rubbers, water based inks or a water based coating compositions, which are consequently also subjects of the invention.
