0P91 Abstract Metal Oxide Slurries Stable high concentration aqueous slurries of pigmentary metal oxide particles having a hydrous oxide surface-treatment comprising alumina, for example alumina surface-treated pigmentary titanium dioxide, may be formed by the use of a specified combination of anionic and amine dispersants and a milling in the presence of grinding elements, for example in a sand mill, to develop suitable viscosity and gloss characteristics. The slurries may show thixotropic properties and are suitable for incorporation in vinyl silk aqueous emulsion paints.
