摘要：
A process for encapsulating pigment dispersions is provided where a pigment is dispersed with a polymeric dispersant in an aqueous solvent system. An acrylate monomer is added and the resultant mixture is polymerized. Optionally, the acrylate monomer may be emulsified in water with an added surfactant or polymeric dispersant and up to 20% acrylic or other vinyl monomers based on the acrylate may be added to acrylate monomer before polymerization. Such encapsulated pigment dispersions may be used in inkjet inks and are stable to heat, aging Lest conditions, and solvent challenges. Prints from these inks have better durability.
