Abstract: 2125672 9312192 PCTABS00022 An electrorheological material containing a carrier fluid and an ionic dye particle component which is an ionically charged compound based on or derived from a conjugated hydrocarbon compound. A preferred ionically charged compound contains at least one aromatic nucleus that has been sulfonated and/or carboxylated to form a negatively charged system which has, in turn, been offset with a positive ion. The electrorheological material is useful for creating aesthetic visual effects and responds quickly to an electric field.
