发明名称 Latex ink containing a latex having a bimodal molecular weight distribution for indirect printing method
摘要 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.

主权项 1. An aqueous inkjet ink comprising a polymer latex having a bimodal molecular weight distribution; wherein the latex has two peak molecular weights W1 and W2, W2 is greater than W1, and W2 minus W1 is at least about 5000; wherein the latex has a melt viscosity of from about 1,250,000 to about 3,000,000 Pa·S at about 130° C.; further wherein the polymer is selected from the group consisting of styrene acrylate copolymers, styrene methacrylates, and styrene vinyl monomers.
