  • Publication number: 20200255570
    Abstract: The polymeric dispersant is a copolymer obtainable by copolymerizing at least a first monomer chosen from a maleimide compound and maleic anhydride, and a second monomer being an ethylenically unsaturated monomer and in case of maleic anhydride, conversion of resulting maleic anhydride units to N-substituted maleimide units, wherein the first monomer comprises a first substituent having a substantially non-polar chain and wherein the second monomer comprises a second, more polar substituent. In one embodiment of the copolymerisation method, first and second monomers are used with copolymerisation parameters r1, r2, such that r1 and r2?0.5. This results in an at least moderately alternating copolymer. The conversion of maleic anhydride units to maleimide may be partial, for instance at least 10%. The polymeric dispersant can be used in an ink dispersion further comprising colorant particles and an aqueous and/or alcoholic carrier liquid.

  • Patent number: 9500998
    Abstract: Disclosed is a liquid toner dispersion which has a relative low shear viscosity between 1.25 and 225 and a relative conductivity between 0.3 and 30. The liquid toner dispersion includes toner particles in a non-polar carrier liquid, as well as a dispersing agent. This liquid toner dispersion is used in a digital printing process including adding dispersing agent during recycling of excess liquid toner dispersion remaining on a development member after patterned transfer of liquid toner dispersion to the imaging member.

  • Patent number: 9170515
    Abstract: This invention is related to a liquid developer dispersion for use in a digital printing apparatus comprising a non volatile carrier liquid, a marking particle and a dispersing compounds, wherein the marking particle in the liquid developer dispersion is stabilized during storage and wherein at fusing two phases are formed. The invention is also related to the use of the developer in a digital printing apparatus and to a method for preparing the liquid developer dispersion.
