    摘要： Disclosed is a phase change ink composition comprising an ink vehicle, a colorant, and a nonpolymeric organic gelator selected from the group consisting of anthracene-based compounds, steroid compounds, partially fluorinated high molecular weight alkanes, high molecular weight alkanes with exactly one hetero atom, chiral tartrate compounds, chiral butenolide-based compounds, bis-urea compounds, guanines, barbiturates, oxamide compounds, ureidopyrimidone compounds, and mixtures thereof, said organic gelator being present in the ink in an amount of no more than about 20 percent by weight of the ink, said ink having a melting point at or below which the ink is a solid, said ink having a gel point at or above which the ink is a liquid, and said ink exhibiting a gel state between the melting point and the gel point, said ink exhibiting reversible transitions between the solid state and the gel state upon heating and cooling, said ink exhibiting reversible transitions between the gel state and the liquid state upon heating and cooling, said melting point being greater than about 35° C., said gel point being greater than said melting point. Also disclosed are imaging processes employing phase change inks containing gelator additives.
