摘要： The present disclosure provides methods and composition directed towards a single batch latex ink-jet ink. In one embodiment, a method of manufacturing a single batch latex ink-jet ink can comprise emulsifying a pigment and a monomer in a solvent, and polymerizing the monomer with a reaction condition sufficient to encapsulate the pigment and sufficient to form individual latex particulates thereby forming a single batch latex ink-jet ink. The ink can contain less than about 0.5 wt % of latex particulates having a diameter of 50 nm or less, can contain about 1 wt % to about 10 wt % of latex particulates having a diameter of about 100 nm to about 250 nm and can contain about 3 wt % to about 5 wt % of encapsulated pigment.

摘要： A method of manufacturing a liquid electrophotographic ink includes: mixing a first portion of a carrier fluid and a resin to form a resin mixture; heating the resin mixture until the resin has melted; cooling the resin mixture to form a resin cake, followed by pulverizing the resin cake to form a resin powder; and mix the resin powder with a pigment and a second portion of carrier fluid in a microfluidizer to form a concentrating ink containing composite particles. An alternate method of manufacturing a liquid electrophotographic ink includes: mixing a pigment with a resin powder; and microfluidizing the mixture together with a carrier fluid in a microfluidizer in a number of passes to form a concentrated ink containing composite particles.

The process includes the steps of, firstly, dispersing the core particles in an aqueous solution; adding a mixture of monomers either before or after the dispersion step; then, polymerizing the monomers in view of obtaining polymer encapsulated particles, wherein the polymer shell of the particle includes polymers or co-polymers that have a functional group FG. Finally, the process includes the step of dispersing the encapsulated particles with surfactants and charge directors in view of obtaining positively charged encapsulated particle dispersions.

摘要： An ink forming method involves preparing a deagglomerated ink or a modified deagglomerated ink. The deagglomerated ink or the modified deagglomerated ink includes at least deagglomerated colorant particles and a liquid component. The deagglomerated colorant particles are chosen from pigment particles each encapsulated with a dispersant. The colorant particles have a particle size ranging from about 50 nm to about 500 nm. Prior to shipping and/or storing the deagglomerated ink or the modified deagglomerated ink, a portion of the liquid component is removed to form a concentrated ink that has a nonvolatile solids content ranging from about 40 wt % to about 90 wt % of the concentrated ink.
