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 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.

摘要： A process for encapsulating pigment dispersions is provided where a pigment is dispersed with a polymeric dispersant in an aqueous solvent system. The free polymer dispersant in the pigment dispersion is limited to less than 0.12 grams per gram of pigment. This dispersed pigment is then encapsulated by adding acrylate monomers and optionally acrylic and vinyl monomers and polymerizing. In the encapsulated pigment dispersion the weight ratio of final free polymer to polymer found to the final encapsulated pigment is less than 0.9. The free polymer dispersant is measured by a centrifugation method and the final free polymer is measured by a density gradient centrifugation method. 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.

摘要： A process for encapsulating pigment dispersions is provided where a pigment is dispersed with a polymeric dispersant in an aqueous solvent system. The encapsulation process is done by adding encapsulating monomers continuously or semi-continuously to the aqueous pigment dispersion. The polymerization initiator is added prior to the addition of encapsulating monomers or at the same time as the encapsulating monomers or a combination of prior and simultaneous addition. 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 excellent durability.

摘要： The present disclosure provides an inkjet ink comprising an aqueous vehicle and an encapsulated pigment dispersion. A process for encapsulating pigment dispersions is provided where a pigment is dispersed with a polymeric dispersant in an aqueous solvent system. The encapsulation process has at least two additions of encapsulating monomers followed by polymerization. To a pigment dispersed with a polymeric dispersant is added an encapsulating monomer(s) and a polymerization initiator is added which forms a stage 1 encapsulated pigment. Then a second encapsulating monomer(s) is added and these monomers are polymerized by a second addition of polymerization initiator, forming a second stage encapsulated pigment. The second encapsulating monomer(s) may be added continuously to the stage 1 encapsulated pigment. 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.
