Abstract

An electrophoretic medium comprises discrete droplets of an electrophoretic internal phase comprising a fluid and carbon black particles in the fluid. The droplets are surrounded by a polyurethane binder formed by a diisocyanate and a polyether diol, at least 20 mole per cent of the diisocyanate being an aromatic diisocyanate.
