RESUMEN:
The invention provides dispersed inorganic mixed metal oxide pigment compositions in a non-aqueous media utilizing a dispersant having terminal end groups and a central portion of the structure —[CH(A)-C(B)(D)]n-[CR2CR2]m- to disperse a mixed metal oxide pigment in the media. 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 subsequently firing the coloured article is also described.
