ABSTRACT:
A composition useful in copying and printing is described. In one embodiment, the composition comprises a purified fraction of uintaite and a thermoplastic polymer. Preferably, the composition comprises a maltene-enriched fraction of uintaite derived by solvent extraction, a thermoplastic polymer and a colorant. In another embodiment, the present invention is an electrophotographic method comprising the steps of generating a latent electrostatic image; developing said latent image with a toner comprising a purified fraction of uintaite; and fixing said toner. The present invention is also a printing ink emulsion comprising a maltene-enriched fraction of uintaite.
