    摘要: A process for depositing marking material onto a substrate which includes (a) providing a propellant to a head structure, the head structure having a channel therein, the channel having an exit orifice with a width no larger than about 250 microns through which the propellant can flow, the propellant flowing through the channel to form thereby a propellant stream having kinetic energy, the 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 includes particles which include a resin and a colorant, the particles having an average particle diameter of no more than about 7 microns and a particle size distribution of GSD equal to no more than about 1.25, wherein the particles are prepared by an emulsion aggregation process.
