摘要:
A phase change ink having an ink vehicle and a conductivity enhancing agent. The conductivity enhancing agent may be an organic salt derived from an organic base having at least one long hydrocarbon chain and an acid. The inks described herein have a consistent electrical conductivity and may be used as an input signal for an ink reservoir level sensing in ink jet devices.
