    Abstract: A process of making a liquid ink comprising the steps of: (a) dissolving a polymer comprising units derived from at least a nitrogen-containing polymerizable monomer in a solvent with a Kauri-Butanol number greater than 30 to form a polymer solution; (b) dispersing colorant pigment particles in said polymer solution to form a colorant pigment dispersion; (c) removing at least some of said solvent from said colorant pigment dispersion to form treated colorant pigment particles; and (d) dispersing said treated colorant pigment particles in an organosol containing a carrier liquid having a Kauri-Butanol number less than 30.

    Abstract: Method and apparatus for producing an image on plain paper from image data using a photoreceptor. An image-wise distribution of charges is produced on the photoreceptor corresponding to the image data. A liquid ink having solid charged pigmented particles, the liquid ink having an effective glass transition temperature of less than 25 degrees Celsius is applied to the photoreceptor forming an image-wise distribution of the pigmented particles on the photoreceptor to form the image. The liquid ink has greater than seventy-five percent by volume fraction of solids in the image. A film forming means is positioned against the photoreceptor immediately following the application means to dry the image of the liquid ink to film forming within 0.5 seconds. The image is dried on the photoreceptor. The image is then transferred to an elastomeric transfer roller which forms a first transfer nip under pressure with the photoreceptor. The elastomeric transfer roller is heated to from 50 degrees Celsius to 100 degrees Celsius. Subsequently, the image is transferred to plain paper through a nip formed between a backup roller under pressure with the transfer roller. The release layer of the photoreceptor has a surface energy which is less than a surface energy of the elastomeric transfer roller which in turn is less than a surface energy of the liquid ink which in turn is less than a surface energy of the plain paper.

    Abstract: A metallic toner fluid composition that contains (A) electrostatically charged, colloidal elemental metal particles dispersed in an electrically nonconductive organic carrier liquid having a dielectric constant less than about 3.5 and a volume resistivity greater than about 10.sup.12 ohm-cm, (B) a soluble surfactant in an amount sufficient to charge and stabilize the colloidal metal dispersion, and (C) an effective amount of organosol particles and/or a soluble polymer that is not a soluble surfactant (B). Also disclosed is a substrate coated with elemental metallic toner fluid particles. The coated substrate can act as a donor substrate for thermal mass transfer of images to a secondary receiving substrate by performing either or both of the following steps, in any order:(a) transferring the elemental metal coating from the primary substrate to the secondary receiving substrate;(b) contacting the elemental metal coated primary or secondary substrate with an electroless metal plating solution.
