CROSS REFERENCE TO RELATED APPLICATIONS
Application U.S. Ser. No. 09/723,778, now U.S. Pat. No. 6,383,561 B1, filed concurrently herewith, entitled “Ballistic Aerosol Marking Process Employing Marking Material Comprising Vinyl Resin and Poly(3,4-ethylenedioxythiophene),” with the named inventors Karen A. Moffat and Maria N. V. McDougall, the disclosure of which is totally incorporated herein by reference, discloses a process for depositing marking material onto a substrate which comprises (a) providing a propellant to a head structure, said head structure having at least one channel therein, said channel having an exit orifice with a width no larger than about 250 microns through which the propellant can flow, said propellant flowing through the channel to form thereby a propellant stream having kinetic energy, said channel directing the propellant stream toward the substrate, and (b) controllably introducing a particulate marking material into the propellant stream in the channel, wherein the kinetic energy of the propellant particle stream causes the particulate marking material to impact the substrate, and wherein the particulate marking material comprises toner particles which comprise a vinyl resin, an optional colorant, and poly(3,4-ethylenedioxythiophene), said toner particles having an average particle diameter of no more than about 10 microns and a particle size distribution of GSD equal to no more than about 1.25, wherein said toner particles are prepared by an emulsion aggregation process, said toner particles having an average bulk conductivity of at least about 10
−11
Siemens per centimeter.
Application U.S. Ser. No. 09/723,577, now U.S. Pat. No. 6,503,678 B1, filed concurrently herewith, entitled “Ballistic Aerosol Marking Process Employing Marking Material Comprising Vinyl Resin and Poly(3,4-ethylenedioxypyrrole),” with the named inventors Karen A. Moffat, Rina Carlini, Maria N. V. McDougall, and Paul J. Gerroir, the disclosure of which is totally incorporated herein by reference, discloses a process for depositing marking material onto a substrate which comprises (a) providing a propellant to a head structure, said head structure having at least one channel therein, said channel having an exit orifice with a width no larger than about 250 microns through which the propellant can flow, said propellant flowing through the channel to form thereby a propellant stream having kinetic energy, said channel directing the propellant stream toward the substrate, and (b) controllably introducing a particulate marking material into the propellant stream in the channel, wherein the kinetic energy of the propellant particle stream causes the particulate marking material to impact the substrate, and wherein the particulate marking material comprises toner particles which comprise a vinyl resin, an optional colorant, and poly(3,4-ethylenedioxypyrrole), said toner particles having an average particle diameter of no more than about 10 microns and a particle size distribution of GSD equal to no more than about 1.25, wherein said toner particles are prepared by an emulsion aggregation process, said toner particles having an average bulk conductivity of at least about 10

Application U.S. Ser. No. 09/724,458 now U.S. Pat. No. 6,503,678 B1, filed concurrently herewith, entitled “Toner Compositions Comprising Polythiophenes,” with the named inventors Karen A. Moffat, Maria N. V. McDougall, Rina Carlini, Dan A. Hays, Jack T. LeStrange, and Paul J. Gerroir, the disclosure of which is totally incorporated herein by reference, discloses a toner comprising particles of a resin and an optional colorant, said toner particles having coated thereon a polythiophene. Another embodiment is directed to a process which comprises (a) generating an electrostatic latent image on an imaging member, and (b) developing the latent image by contacting the imaging member with charged toner particles comprising a resin and an optional colorant, said toner particles having coated thereon a polythiophene.
Application U.S. Ser. No. 09/723,839 now U.S. Pat. No. 6,492,082 B1, filed concurrently herewith, entitled “Toner Compositions Comprising Polypyrroles,” with the named inventors Karen A.
