  • Publication number: 20140332729
    Abstract: The present invention relates to the field of inks for electrophoretic display devices, and more particularly to a process for encapsulating at least one inorganic pigment by dispersion polymerization in an organic medium. The process consists in dispersing the inorganic pigment in the organic medium, then in synthesizing at least one stable polymer latex in said organic medium, said latex precipitating around said inorganic pigment in order to form a protective shell and to thus obtain a particle, said synthesis of the latex being carried out by polymerization, in said organic medium, of an electrostatically chargeable functional monomer, based on use of a macroinitiator capable of stabilizing said particle obtained.
