Abstract: 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.
