发明名称 | Liquid toner dispersion and use thereof | ||
摘要 | A liquid toner dispersion provided with marking particles comprising a pigment and a polyester based resin. The dispersion includes a nonpolar organic solvent and a hyperdispersant including a graft copolymer provided with an anchor group including an amine-functionalized polymer onto which at least one stabilizing group is grafted. The stabilizing group includes a hydroxylated fatty acid oligomer. The amine-functionalized polymer has a weight-average molecular weight of less than 1000 g/mol. | ||

主权项 | 1. A liquid toner dispersion provided with marking particles comprising a pigment and a resin, said dispersion comprising a nonpolar organic solvent and a hyper-dispersant comprising a graft copolymer provided with an anchor group comprising an amine-functionalised polymer, wherein the amine-functionalised polymer has 3-25 binding sites in the form of nitrogen atoms, onto which at least one stabilising group is grafted, wherein the amine-functionalised polymer has an weight-average molecular weight of in the range of 100-1000 g/mol, wherein said stabilising group comprises an oligomer of hydroxylated fatty acids, of which a carboxylic acid group is coupled to a binding site of the amine-functionalised polymer and wherein the graft copolymer has a weight-average molecular weight in the range of 1500-40,000 g/mol. | ||
