摘要:
The disclosed embodiments are directed to a composition of an inverse emulsion acrylate ink for use in variable data digital lithographic image forming devices and methods for preparing and using the ink. The disclosed inverse emulsion acrylate ink includes an acrylate monomer, oligomer, polymer, or mixtures thereof that is a continuous phase, and water dispersed as an emulsion in the continuous acrylate phase. The disclosed inverse emulsion acrylate ink includes one or more of a color pigment component, a rheology modifying agent, a stabilizing agent, and a photoinitiator component. The water may be supplemented with a surfactant to lower a surface tension of the water.

An aqueous latex ink includes a polymer latex having a particle size of less than about 100 nm. A method of making an aqueous latex ink includes emulsifying a polymer without the use of a surfactant to prepare a latex having a particle size of less than 100 nm. A method of printing an image on a substrate includes applying an aqueous latex ink to an intermediate receiving member using an inkjet printhead, spreading the ink onto the intermediate receiving member, inducing a property change of the ink, and transferring the ink to a substrate, wherein the ink comprises a latex having a particle size of less than about 100 nm.
摘要:
An ink comprising a first reactive latex having a first crosslinkable functional group and a second reactive latex a second crosslinkable functional group, wherein the first reactive latex can react with the second reactive latex to form a cross-linked polymer matrix when in contact with each other, wherein the first reactive latex and the second reactive latex are not in contact with each other, which is suitable for use in an indirect printing method, and a method of printing using the ink.

An aqueous inkjet ink includes a latex having a bimodal molecular weight distribution. A method of making an aqueous inkjet ink includes adding a dispersion of surfactant and carbon black to a reactor, adding a latex having a bimodal molecular weight to the reactor resulting in a reaction mixture, and homogenizing the reaction mixture, forming the ink. A method of printing an image to a substrate includes applying an aqueous inkjet ink onto an intermediate receiving member using an inkjet printhead, spreading the ink onto the intermediate receiving member, inducing a property change of the ink, and transferring the ink to a substrate, wherein the ink includes a latex having a bimodal weight distribution.
摘要:
A method for preparing a pigment dispersion includes milling a starting pigment dispersion containing a pigment and optionally a carrier and a dispersant with milling media having an average particle size of about 100 μm or less, until a final pigment dispersion having at least one of a desired pigment average particle size and a desired pigment particle size distribution is obtained; optionally separating the milling media from the final pigment dispersion; and optionally diluting the final pigment dispersion to obtain a desired pigment particle concentration.
