摘要:
A ballistic aerosol marking device includes, marking material which flows from a material reservoir to a delivery channel via a port. Flow of marking material is facilitated by the creation of a fluidized bed or aerosol of marking material in the reservoir. Gas flow together with mechanical or electromechanical assistance can be used to assist in the generation of the fluidized bed or aerosol.
摘要:
In a ballistic aerosol marking device or the like, marking material flows from a material reservoir to a delivery channel via a port. Flow of marking material is facilitated by the provision of electrostatic marking material moving structures in or near the walls of the marking material reservoir. Marking material may be set into a continuous motion past the port and controllably extracted from the reservoir into the channel.
摘要:
A method for treating a substrate is disclosed in which a propellant stream is passed through a channel and directed toward a substrate. Substrate pre-marking or post-marking treatment material is controllably introduced into the propellant stream and imparted with sufficient kinetic energy thereby to be made incident upon a substrate. A multiplicity of channels for directing the propellant and treatment material allow for high throughput, high resolution in-situ treatment. Marking materials and treatment materials may be introduced into the channel and mixed therein prior to being made incident on the substrate, or mixed or superimposed on the substrate without registration. One example is a single-pass, full-color printer.

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.

摘要:
Toner particles are provided which may, in embodiments, include a core and a shell. In embodiments, charge control agents may be co-emulsified with a resin utilized to form a shell. The shell may prevent a crystalline resin in the core from migrating to the toner surface. Inclusion of the charge control agent in the shell itself may provide the resulting toner particles with desirable charge characteristics and sensitivity to relative humidity.
