Abstract
A process for the preparation of ink compositions comprising the emulsion polymerization of monomer, water, surfactant, and initiator with stirring and heating to provide a latex; mixing therewith a pigment dispersion of pigment particles, water, and cationic surfactant; blending the mixture; thereafter stirring the mixture; and subsequently adding additional anionic surfactant to stabilize the aggregate particles.
