Abstract:
1. A method of making a liquid toner comprising: dispersing fibrous toner particles in carrier liquid, said carrier liquid having, as a major component, a first liquid hydrocarbon having a first rate of evaporation; and adding a second liquid hydrocarbon to said carrier liquid as a minor component, the second liquid hydrocarbon having a second rate of evaporation which, at room temperature, is at least an order of magnitude less than the first rate of evaporation, wherein, said fibrous toner particles comprise a polymer portion and pigment dispersed in said polymer portion, said polymer portion comprising a surface of said fibrous toner particles and being insoluble in said carrier liquid at temperatures below 40 degrees Celsius so that the polymer portion will not dissolve or solvate in storage, and solvatable by said carrier liquid only at temperatures above 50 degrees Celsius.
