  • Publication number: 20140292943
    Abstract: The ink set of the invention includes a first ink composition and a second ink composition. The first ink composition contains a first pigment and an alkanediol having 6 or less carbon atoms and having a normal boiling point of 245° C. or more. The content of the first pigment is 1.5% by mass or more, and the content of the alkanediol is 3% by mass or more and 20% by mass or less. The second ink composition contains a second pigment and a penetrant other than the alkanediol. The content of the second pigment is less than 1.5% by mass. The penetrant contained in the second ink composition has an osmotic force higher than that of the alkanediol contained in the first ink composition.

  • Publication number: 20140296395
    Abstract: 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.
