Abstract:
1. A phase separation ink comprising: at least one crystallizable component comprising a material that crystallizes as it cools from a first ink jetting temperature to a second temperature that is lower than the ink jetting temperature, wherein the second temperature is sufficient to initiate crystallization of the at least one crystallizable component; at least one amorphous component comprising a material that remains amorphous at the second temperature; and 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 at least one crystallizable component is diphenethyl L-tartrate and the at least one amorphous component is di-L methyl L-tartrate; or wherein the at least one crystallizable component is Bis(4-methoxyphenyl) octanedioate and the at least one amorphous component is tri-DL-menthyl citrate.
