Synthetic isoparaffinic hydrocarbons have a 40+ year history as safe, high performance carrier fluids in liquid toners. A historical perspective of liquid photocopy is given as well as a review of liquid toner benefits. New technologies have introduced new performance requirements for carrier fluids, in addition to traditional fluid requirements. Hydrocarbon structures are reviewed as well as their relationship to addressing these new performance requirements. The health and environmental impact of using aliphatic hydrocarbons in non-impact printing applications is reviewed.
