| 摘要 |
The present invention relates to a method for preparing a stable dispersion of a metal oxide in water comprising dispersing colloidal microcrystalline cellulose in water either prior to or concurrently with adding the metal oxide and recovering the stable metal oxide dispersion, wherein: (i) the metal oxide has an average particle size of less than 250 nanometers, (ii) the metal oxide is not iron oxide, (iii) the colloidal microcrystalline cellulose is coprocessed with a polymeric binder and (iv) the metal oxide is present in an amount of at least 0.6% by weight of the total weight of the dispersion. |
