    摘要: An in situ process for preparing a phase change magnetic ink including combining a phase change ink composition with a reducing agent; wherein the phase change ink composition comprises a carrier, an optional colorant, and an optional dispersant, and wherein the reducing agent has at least one alcohol functionality; heating the combined phase ink composition and reducing agent to a first temperature sufficient to provide a melt composition; adding a metal salt to the melt composition under an inert atmosphere to provide a metal salt-melt composition; heating the metal salt-melt composition to a second temperature sufficient to effect a metal reduction reaction to reduce the metal salt to metal nanoparticles thus forming in situ a phase change magnetic ink including the metal nanoparticles; optionally, filtering the phase change magnetic ink while in a liquid state; cooling the phase change magnetic ink to a solid state.

    摘要: Disclosed is a phase change black ink composition comprising (1) a low polarity ink carrier comprising (A) an ester-terminated polyamide, (B) a Guerbet alcohol or a Guerbet alcohol mixture including at least one linear alcohol, and (C) a low polarity wax, and (2) a black colorant. The ink carrier can also include a dispersant. The ink is resistant to aggregation and settling of the black colorant when a standby-mode printer temperature for the ink is not more than about the gel temperature of the ink.
