    摘要： Ink jet inks and liquid developers are disclosed which contain coloured 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 coloured silica particles. The liquid developers generally comprise a liquid medium, a resin, a pluraltiy of the coloured 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： Disclosed are ionographic imaging apparatuses and processes. One apparatus comprises an imaging means (1), means (5) for applying to the imaging means a liquid material capable of forming a dielectric peel layer adhering to the imaging means, ionographic writing means (7) for generating a latent image on the peel layer, means (9) 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 (15) 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 transferring the fully formed image to a substrate, wherein the developers employed contain a release agent.

    摘要： Disclosed is an electrophotographic liquid developer composition comprising a liquid medium, first toner particles able to be charged to one polarity and comprising a first dye and polymeric cores to which steric stabilizer polymers have been attached, second toner particles able to be charged to a polarity opposite to that of the first toner particles and comprising a second dye of a different color from that of the first dye and polymeric cores to which steric stabilizer polymers have been attached, and a charge director. The disclosed developer is suitable for developing electrostatic latent images in two different colors in a single development step. The latent image comprises three areas of charge; toner particles of one color are selectively attracted to one area, toner particles of the other color are selectively attracted to the second area, and the third area remains undeveloped as a background area.
