Application 10/711,278
(a) reacting the particle with a reagent having a functional group
capable of reacting with, and bonding to, the particle, and also having
a polymerizable or polymerization-initiating group, thereby causing
the functional group to react with the particle surface and attach the
polymerizable group thereto;
(b) reacting the product of step (a) with at least one monomer or
oligomer under conditions effective to cause reaction between the
polymerizable or polymerization-initiating group on the particle and
the at least one monomer or oligomer, thereby causing the formation
of polymer bonded to the particle; and
(c) dispersing the polymer-coated pigment particle into a suspending
fluid to form an electrophoretic medium.
35. A process for producing a polymer-coated titania particle, which
process comprises:
(a) reacting the titania particle with a reagent having a functional
group capable of reacting with, and forming a covalent bond to, the
particle, and also having a polymerizable or polymerization-initiating
group, thereby causing the functional group to react with the particle
surface and attach the polymerizable group thereto via a covalent
bond; and
(b) reacting the product of step (a) with at least one monomer or
oligomer under conditions effective to cause reaction between the
polymerizable or polymerization-initiating group on the titania
particle and the at least one monomer or oligomer, thereby causing the
formation of polymer bonded to the titania particle.
