<p>A method of producing a shear-thinning silica dispersion for an inkjet ink comprising: providing a composition comprising fumed silica, an organic solvent and/or a reactive diluent and a radiation-curable oligomer and/or a passive thermoplastic resin; bead milling the composition using milling beads having a mean diameter of 0.3 to 1.0 mm, wherein the ratio of the volume of milling beads present in the composition during bead milling in mL to the weight of the composition in grams is 0.5 to 2.0:1.0, and wherein the viscosity of the composition during bead milling is 50-800 mPasat 1,000 s; and removing the composition from the mill.</p> |
