Patent ID: 8526099

Claim:
A method of manufacturing microcapsules, individual microcapsules including a capsule shell and an electrophoretic dispersion liquid encapsulated by the capsule body, the capsule shell being made of an organic polymer, the electrophoretic dispersion liquid including electrophoretic particles in a dispersion medium, the method comprising: forming droplets of the electrophoretic dispersion liquid by dispersing the electrophoretic dispersion liquid in a polar dispersion medium; and forming an entirety of each capsule shell as a result of polymerizing a polymerizable surfactant in the presence of a polymerization initiator by mixing the polymerization initiator and the polymerizable surfactant with the polar dispersion medium, the polymerizable surfactant having a hydrophilic group, a hydrophobic group and a polymerizable group, so as to coat the droplets with the polymerizable surfactant and inducing a polymerization reaction to form the organic polymer, thereby obtaining the microcapsules.
