摘要： Methods of leveling ink on substrates and apparatuses useful in printing are provided. An exemplary embodiment of the methods includes irradiating ink disposed on a first surface of a porous substrate with radiation emitted by at least one flash lamp. The radiation flash heats the ink to at least a viscosity threshold temperature of the ink to allow the ink to flow laterally on the first surface to produce leveling of the ink. The ink is heated sufficiently rapidly that heat transfer from the ink to the substrate is sufficiently small during the leveling that ink at the substrate interface is cooled to a temperature below the viscosity threshold temperature thereby preventing any significant ink permeation into the substrate from the first surface.

摘要： Ink jet inks and liquid developers are disclosed which contain colored particles comprising hydrophilic silica particles, to the surfaces of which dyes are covalently bonded through silane coupling agents. The ink jet inks generally comprise a liquid medium and a plurality of the colored silica particles. The liquid developers generally comprise a liquid medium, a resin, a plurality of the colored silica particles, and a charge control agent. The particles are prepared by a process which comprises reacting hydrophilic silica particles with a silane coupling agent in the absence of water to form particles having covalently attached thereto coupling agents, followed by reacting a dye with the coupling agent attached to the silica particles.

摘要： A suspension polymerization process for the preparation of a polymeric material formed from at least two monomers, a non-gaseous monomer and a gaseous monomer. The composition of the beads or particles of the polymeric material is controlled by adding gaseous monomer to the vapor phase after polymerization of about 5% to about 90% by weight of the non-gaseous monomer or by removing a portion or substantially all of the gaseous monomer in the vapor phase before polymerization of about 70% by weight of the gaseous monomer in the aqueous suspension, or a combination thereof.

摘要： Disclosed are ionographic imaging apparatuses and processes. One apparatus comprises an imaging means, means for applying to the imaging means a liquid material capable of forming a dielectric peel layer adhering to the imaging means, ionographic writing means for generating a latent image on the peel layer, means for developing the latent image on the peel layer, and means for simultaneously transferring the peel layer bearing the developed image from the imaging means to a substrate and affixing the peel layer bearing the developed image to the substrate. In another embodiment, the apparatus employs a process which comprises applying to an imaging means a liquid material capable of forming a dielectric peel layer adhering to the imaging means, forming a first latent image on the peel layer with an ionographic writing means, developing the first latent image with a first developer, forming a second latent image on the peel layer containing the first developed image with an ionographic writing means, developing the second latent image with a second developer, forming a third latent image on the peel layer containing the first and second developed images with an ionographic writing means, developing the third latent image with a third developer, and simultaneously transferring the portion of the peel layer that bears the developed images to a substrate and affixing the peel layer bearing the developed images to the substrate. A further embodiment is directed to an apparatus and process for sequentially forming and developing primary color images on an imaging means to form a full color image, followed by trasnsferring the fully formed image to a substrate, wherein the developers employed contain a release agent.
