Abstract
The invention provides dispersed inorganic mixed metal oxide pigment compositions in a non-aqueous media utilizing a polyester dispersant having a terminal hydroxyl, tertiary amine or quaternized amine anchoring group and a mixed metal oxide pigment. The metal oxide pigment is of the type used to colour ceramic or glass articles. A milling process using beads is also described to reduce the mixed metal oxide particle size to the desired range. A method of using the mixed metal oxide dispersion to digitally print an image on a ceramic or glass article using the dispersion jetted through a nozzle and firing the coloured article is also described.
