  • Publication number: 20080014513
    Abstract: Disclosed herein is a xerographic print comprising a substrate with a toner-based image printed thereon, the printed substrate including low surface tension portions having a surface tension of no more than about 22 mN/m at 25 Deg. C. resulting in a surface tension gradient field on the substrate, the printed substrate being coated with a coating comprising at least one surfactant and a film-forming polymer, the coating having a liquid phase surface tension at 25 Deg. C. not exceeding the surface tension of the low surface tension portions of the printed substrate by more than about 2 mN/m, the coating having substantially no pinholes and being sufficiently resistant to permeation by the fuser oil to exhibit an effective absence of haze 24 hours after application. A system and a method of applying a substantially pinhole-free and haze-free coating substantially immediately after print fusing also are disclosed.

  • Publication number: 20070122728
    Abstract: A method for forming toner particles includes polymerizing monomers to form a latex comprising polymer particles; combining the latex with unsaturated curable resin to form aggregates containing the polymer particles and the unsaturated curable resin particles; and heating the aggregates to form coalesced particles. A toner composition that may be formed by the process described herein contains toner particles containing polymer containing photoinitiator and unsaturated curable resin. Another toner composition that may be formed by the process described herein contains toner particles containing unsaturated curable resin and, on the surface of the toner particles, photoinitiator.

  • Publication number: 20070111128
    Abstract: Embodiments include a chemical toner composition having a first resin including a styrene vinyl copolymer and having a Tg of from about 46 to about 56° C., b) a second resin including a styrene vinyl copolymer having a Tg of from about 55 to about 65° C., c) a distilled wax having a heat of crystallization and a heat of enthalpy, both from about 1.0 to about 4.0 J/g for every weight percent of the wax used in the chemical toner composition, and wherein the wax has a peak melting point of from about 70 to about 99° C., and d) a colorant, wherein the chemical toner has a gloss of from about 30 to about 80 GGU.

  • Publication number: 20070042286
    Abstract: A toner process comprising aggregating or coagulating a latex emulsion comprising a resin, a colorant and wax particles using an amount of polymetal ion coagulant to provide core particles; heating the core particles to provide micron size aggregates; optionally adding a second resin emulsion; adding a sequestering or complexing component and a base to remove the polymetal ion in a controlled manner; further heating the mixture to provide toner particles; and optionally, isolating the toner particles.

  • Publication number: 20060286476
    Abstract: Provided are a latex process and a toner process, both of which include the preparation of a latex having weight average molecular weight of from about 12×103 to about 24×103. The latex is manufactured under monomer-starved polymerization condition such as monomer feeding rate equal to or less than 0.5166% per minute by weight of the monomer(s) to be fed. The toners prepared according to the present disclosure have gained improved properties such as gloss, fusing performance, crease performance, stripping performance, document offset, vinyl offset, and parent charging etc.

  • Patent number: 4809961
    Abstract: A fixture holds a workpiece in a plurality of orientations. The fixture is operable to flip the workpiece into a plurality of positions for work to be performed thereon. Each workpiece is mounted at the end of the spindle and secured thereat by a workpiece holder which takes a variety of forms depending on the size and shape of the workpiece.
