Abstract: An adhesive composition comprising a polyurethane and a cationic polymeric dopant or a polymerizable cationic dopant may be used to form one or more adhesive layers of electro-optic assemblies. They enable improved electro-optic performance of the corresponding; electro-optic devices even at low temperatures.

Abstract: An electrophoretic display comprising a fluid including a first species of particles and a charge control agent disposed between first and second electrodes. When a first addressing impulse have an electrical polarity is applied to the medium, the first species of particles move in one direction relative to the electric field, but when a second addressing impulse, larger than the first addressing impulse but having the same electrical polarity, is applied to the medium, the first species of particles move in the opposed direction relative to the electric field.

Abstract: Improvements in the production of electro-optic displays include: (a) use of a masking film to keep a selected area of a backplane (such as a front electrode contact) free from electro-optic material; (b) spray coating of electrophoretic capsules on to a substrate under controlled conditions; (c) forming a monolayer of capsules on a substrate by prior deposition of a water-swellable polymer; and (d) overcoating a layer of electro-optic material with a solvent-free polymerizable liquid material, contacting this layer with a light-transmissive electrode layer, and polymerizing the liquid material to adhere the electrode layer to the electro-optic material.

Abstract: A process for the preparation of colored polymeric toner particles includes: forming an organic phase by dissolving an organic polymer and, optionally, one or more additives in a water-immiscible organic solvent; forming a dispersion by combining the organic phase with an aqueous phase comprising a particulate stabilizer, a colorant, and, optionally, a promoter, with the proviso that when the colorant is carbon black, it is an acidic carbon black having a pH less than 7; homogenizing the dispersion to form droplets containing the organic solvent, organic polymer, and colorant; removing the organic solvent from the droplets to form colored polymeric toner particles; and separating and drying the toner particles.
