    摘要： Disclosed is an apparatus for depositing a particulate marking material onto a substrate, comprising (a) a printhead having defined therein at least one channel, each channel having an inner surface and an exit orifice with a width no larger than about 250 microns, the inner surface of each channel having thereon a hydrophobic coating material; (b) a propellant source connected to each channel such that propellant provided by the propellant source can flow through each channel to form propellant streams therein, said propellant streams having kinetic energy, each channel directing the propellant stream through the exit orifice toward the substrate; and (c) a marking material reservoir having an inner surface, said inner surface having thereon the hydrophobic coating material, said reservoir containing particles of a particulate marking material, said reservoir being communicatively connected to each channel such that the particulate marking material from the reservoir can be controllably introduced into the propellant stream in each channel so that the kinetic energy of the propellant stream can cause the particulate marking material to impact the substrate, wherein either (i) the marking material particles of particulate marking material have an outer coating of the hydrophobic coating material; or (ii) the marking material particles have additive particles on the surface thereof, said additive particles having an outer coating of the hydrophobic coating material; or (iii) both the marking material particles and the additive particles have an outer coating of the hydrophobic coating material.

    摘要： A process for the preparation of toner compositions with controlled particle size comprising:(i) preparing a pigment dispersion in water, which dispersion is comprised of a pigment, an ionic surfactant in amounts of from about 0.5 to about 10 percent by weight to water, and an optional charge control agent;(ii) shearing the pigment dispersion with a latex mixture comprised of a counterionic surfactant with a charge polarity of opposite sign to that of said ionic surfactant, a nonionic surfactant, and resin particles, thereby causing a flocculation or heterocoagulation of the formed particles of pigment, resin, and charge control agent;(iii) stirring the resulting sheared viscous mixture of (ii) at from about 300 to about 1,000 revolutions per minute to form electrostatically bound substantially stable toiler size aggregates with a narrow particle size distribution;(iv) reducing the stirring speed in (iii) to from about 100 to about 600 revolutions per minute, and subsequently adding further anionic or nonionic surfactant in the range of from about 0.1 to about 10 percent by weight of water to control, prevent, or minimize further growth or enlargement of the particles in the coalescence step (v);(v) heating and coalescing from about 5.degree. to about 50.degree. C. above about the resin glass transition temperature, Tg, which resin Tg is from between about 45.degree. C. to about 90.degree. C., the statically bound aggregated particles to form said toner composition comprised of resin, pigment and optional charge control agent;(vi) washing the aggregated particles at a temperature of from about 15.degree. C. to about 5.degree. C. below the glass transition temperature of the resin, and subsequently filtering the aggregated particles until substantially all of the surfactant has been removed from the aggregated particles, followed by subsequent driving of the particles at a temperature of from about 15.degree. C. to about 5.degree. C. below the glass transition temperature of the resin; and(vii) subsequently adding to said toner product a first layer of a hydrophilic oxide, and a second layer of a hydrophobic oxide.
