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.

Abstract: The present invention relates to a dispersant having a tertiary or quaternary amine anchoring group and a solubilizing polymer selected from C8-50 fatty acid; a C8-50 ak(en)yl substituted succinic acid, anhydride or partial ester; a dimer or trimer fatty acid; and/or polymers from repeating units of polyesters, polyethers, polyacrylate, polyamides, polyurethanes or mixtures of said repeating units in a random or blocky copolymer. The dispersants are an improvement in that the alkylene connecting group between the tertiary or quaternized amine and the solubilizing polymer lacks abstractable hydrogen atoms at the geminal carbon atom from the nitrogen of the tertiary or quaternized amine over the prior art. The dispersants are useful as dispersants with improved thermal stability and low amounts yellow color after aging at elevated temperatures.
