  • Publication number: 20080100684
    Abstract: Phase change ink comprising an ink vehicle that includes at least one amphiphilic molecule. The amphiphilic molecule is capable of co-crystallizing into the at least one wax monomer to form functionalized spherulites which are then capable of hydrogen bonding to other similarly functionalized spherulites to form a bonded network of spherulites. Increased adhesive and cohesive strength of the ink on paper can result, thereby generating a robust image.

  • Patent number: 6811598
    Abstract: An ink composition having an array of encapsulating particles contained within a liquid medium. The encapsulating particles encapsulate one or more pigment particles. The ink composition is prepared and formulated such that the density of the encapsulating particles approximate the density of the liquid medium containing the encapsulating particles such that a neutral buoyancy is achieved. More particularly, in a case where the liquid medium is water, the density of the encapsulating particles ranges from 0.9 g/cc to 1.1 g/cc.
