Synthesis of Novel Encapsulated Pigment Dispersion

Encapsulated Pigment that each pigment particle is coated with water-insoluble polymeric materials has been studied. In spite of e several advantages of encapsulated pigment, there are some issues of applications due to the problems for a synthetic method. There are poor dispersion stability of reactant pigment, low adhesion force between monomer and pigment, and surfactant residue in solution.To overcome these problems, we adopted emulsion polymerization using anionic self-dispersed pigment, basic monomer, and macromonomer to offer dispersion stability, electrostatic adhesion force and surfactant free reactionAs a result, we developed good dispersion stability, proper size encapsulated pigment.
