Abstract
Broadly the invention provides for a deinkable toner composition, an image made with the deinkable toner, and a method for making the toner including a coloring agent; a thermoplastic polymer; and a protein. In another embodiment the toner includes a coloring agent and a thermoplastic polymer where the protein has been incorporated into the polymer itself. In typical embodiments the protein is derived from soybeans but may be from other plant or animal sources. Typically the toner has a positive triboelectric charge of between about 10 to about 40 microCoulomb/g, or a negative triboelectric charge of between about 10 to about 40 microCoulomb/g.
