RESUMEN:
The invention provides dispersed inorganic mixed metal oxide pigment compositions in a hydrocarbon media utilizing a dispersant having polyisobutylene succinic anhydride structure reacted with a non-polymeric amino ether/alcohol to disperse a mixed metal oxide pigment in the media. The metal oxide pigment is of the type used to color 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 colored article is also described.
