Patent ID: 6986976

Claim:
A liquid electrophotographic ink comprising a liquid carrier, having a Kauri-Butanol number less than 30 and comprising at least some C 10 , C 11 and C 12 hydrocarbons, a polymeric binder, a colorant, and a fluid material having an antagonistic odor vector for C 10 , C 11 and C 12 hydrocarbons, wherein the hydrocarbons have a vapor pressure measured in mm Hg at 60° C., and the fluid material that has an antagonistic odor vector for the C 10 , C 11 and C 12 hydrocarbons has a vapor pressure in mm of Hg at 60° C. within the range of 40–160% of the vapor pressure of the C 10 , C 11 and C 12 hydrocarbons; and wherein the fluid material having an antagonistic odor vector is selected from the group consisting of terpenoids, ionones, pentenones, cyclopentadecanones, ketones, cyclohexanecarboxylates, benzoyl benzoates, alkanoyl benzoates, alpha-keto esters, 2-indanmethanol and its derivatives, substituted cycloheanols, (tetra-hydrocarbyl-substituted-phenyl)alkanes, dihydrobenzofuranones, alkyl-substituted pyridine, campholinic aldehyde derivatives, and macrocylcic lactones.
