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-functionalised polymer onto which at least one stabilising group is grafted. The stabilising group includes a hydroxylated fatty acid oligomer. The amine-functionalised polymer has a weight-average molecular weight of less than 1000 g/mol. |
