    • 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 derivative present 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.

    • A particulate composition comprising, A) an organic phase change material, B) a water insoluble polymeric matrix comprising, B1) polymeric material containing repeating monomer units formed from i) at least one hydrophobic ethylenically unsaturated monomer(s), and ii) at least one hydrophilic ethylenically unsaturated monomer(s) which provides the polymeric material with pendent functional groups, and, B2) a cross-linking component derived from a cross-linking compound which has reacted with said pendent functional groups of the polymeric material, in which the organic phase change material (A) is distributed as a separate phase throughout the water insoluble polymeric matrix (B). The invention also relates to a process of providing a particulate composition employing the steps, 1) providing an aqueous phase containing dissolved polymeric material which polymeric material contains repeating monomer units of i) at least one hydrophobic ethylenically unsaturated monomer(s), and ii) at least one hydrophilic ethylenically unsaturated monomer(s) which provides the polymeric material with pendent functional groups, 2) emulsifying the organic phase change material into the aqueous phase to form an oil in water emulsion comprising a dispersed phase of organic phase change material and a continuous aqueous phase, 3) introducing a cross-linking compound, 4) subjecting the oil in water emulsion to spray drying to evaporate water and form the particulate composition. The particulate composition can be used in a variety of thermal energy regulation or storage applications in for instance textiles, foamed articles, construction articles and electrical equipment.
