  • Patent number: 8912249
    Abstract: 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 and a polyurethane dispersion are added and the resultant mixture is polymerized. Optionally, the acrylate monomer/polyurethane mixture 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 the acrylate monomer/polyurethane mixture before polymerization. Such encapsulated pigment dispersions may be used in inkjet inks and are stable to heat, aging test conditions, and solvent challenges. Prints from these inks have better durability.
