  • REVERSIBLE POLYMERS IN 3-D PRINTING
    Publication number: 20150337147
    Abstract: An ink jettable 3-D material composition includes a reversible polymer material, which can reversibly transition between a liquid state and a solid state by reversible cyclo-addition reactions, wherein upon cooling, the reversible polymer material transitions from a liquid state to a solid state by reversible cyclo-addition reactions within a time period of less than about 10 seconds.

  • Pigmented magenta and yellow phase change inks
    Patent number: 8758494
    Abstract: A solid ink composition comprises a crystalline compound, an amorphous compound and a pigment concentrate. The pigment concentrate includes a diester crystalline compound, a dispersant and a pigment (magenta/yellow). The incorporation of such pigment concentrate in the solid ink composition produces a stable ink.
