ABSTRACT:
A hybrid liquid toner composed of a mixture of two different types of liquid toner. One type is a liquid toner that includes a complex amphipathic molecule of which at least a fixer and a dispersant are polymeric moieties and which additionally includes a charge director and optionally includes a color agent, all of these being carried by a volatile organic solvent of high electrical resistivity. The other type of liquid toner is one that includes a fixer and a dispersant as separate chemical entities and further includes a charge director, a pigment type color agent and a carrier solvent such as mentioned above. The two toners can be mixed in a very wide range of proportions and when so mixed have several advantages which makes the hybrid toner particularly useful in connection with preparation of lithographic masters and microfiche reproductions by electrostatography as well as useful as an all purpose liquid toner.
