  • Inks with colored resin emulsion particles
    Patent number: 6251987
    Abstract: An aqueous ink jet ink composition comprised of water, colorant, and colored resin emulsion particles generated from olefinic monomers, wherein at least one of said olefinic monomers contains a colorant, wherein the olefinic colorant component is prepared from the condensation reaction of a functional colorant with an olefinic containing reactive material, and which reaction generates: wherein Dye represents a colorant chromophore, and R is a carbonyl, carboxylate, oxygen, or arylene, and R′ is hydrogen or alkyl.

  • Ink composition for ink jet printing
    Patent number: 6124376
    Abstract: Disclosed is a process which comprises incorporating into an ink jet printing apparatus an ink composition which comprises water, a colorant, and a polymer of the formula ##STR1## wherein m, n, x, and y are each integers representing the number of repeat monomer units, and wherein the ratio of x:y is from about 10:90 to about 90:10, and causing droplets of the ink to be ejected in an imagewise pattern onto a recording sheet.

  • Toner miniemulsion process
    Patent number: 5766817
    Abstract: A process for the preparation of toner involving(i) aggregating a colorant dispersion with a latex miniemulsion containing polymer, an ionic surfactant, a cosurfactant, and a nonionic surfactant;(ii) coalescing or fusing the aggregates generated; and optionally(iii) cooling, isolating, washing, and drying the toner, and wherein the polymer in said miniemulsion is of a diameter of from about 50 to about 500 nanometers.

  • Ink jet ink compositions and recording processes
    Patent number: 5641346
    Abstract: An ink jet ink includes a colorant and a liquid component containing at least one of an epoxy and a vinyl ether. Water may also be dissolved in the liquid component. Preferably, the vinyl ether is ethylene glycol monovinyl ether. An ink jet recording process includes the steps of ejecting an ink jet ink, such as the inks of the present invention, from an orifice to form an image on a recording medium.
