Abstract

A phase separation ink including at least one crystallizable component that crystallizes as it cools from a first ink jetting temperature to a second lower temperature; at least one amorphous component comprising a material that remains amorphous at the second temperature; an optional colorant; wherein the at least one crystallizable component and the at least one amorphous component are in a molten, single phase state at the first ink jetting temperature; wherein at the second temperature, the phase separation ink comprises a crystalline phase comprising the at least one crystallizable component and an amorphous phase comprising the at least one amorphous component; wherein the amorphous phase of the at least one phase separation ink substantially penetrates into the final image receiving substrate and the crystalline phase of the at least one phase separation ink substantially remains on the surface of the final image receiving substrate.
