Abstract

An electrophoretic suspension prepared in ac-cordance with the present invention includes a dielec-tric fluid having suspended therein a pluraliy of pig-ment particles movable between the electrodes (24, 26) of an EPID device (10) in response to an elec-tric potential applied thereto and an effective amount of at least one additive for chemically absorbing at least one gas in the fluid. To absorb hydrogen gas in the dielectric fluid, a hydrogen absorbing additive is dispersed therein. The molecule of the hydrogen ab-sorbing additive has an aromatic C/H ratio of 1/0.8 or less, and preferably between 1/0.67 and 1/0.75. To ab-sorb chlorine gas in the dielectric fluid, and effective amount of a chlorine gas absorbing compound is also preferably added thereto. The chlorine gas absorbing additive has a molecule having at least one double bond and may be sterically strained alkene such as 5-ethylidene-2-norbornene.
