    摘要： The invention provides dispersed inorganic mixed metal oxide pigment compositions utilizing a carboxylic acid, containing dispersant and a mixed metal oxide pigment. The metal oxide pigment is of the type used to colour ceramic or glass articles. The dispersant, in addition to at least one carboxylic acid group, comprises at least one 300-3000 g/mole solubilizing chain of repeating units from hydrocarbylene or repeating units from C3 or C4 alkylene ethers or mixtures of said ethers. 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.

    摘要： The surface of fine pigment particles is efficiently treated using low energy without causing a cost increase. Provided is a method of treating the surface of fine pigment particles, characterized by maintaining a small gap of 1 mm or narrower between two treating surfaces which are able to get close to and apart from each other and relatively rotate and using the gap between the two treating surfaces which is kept so narrow, as a passage for a fluid to be treated, thereby forming a thin film of the fluid to be treated (forced thin film) . Fine pigment particles are formed in this thin-film fluid (forced thin film) . The method is further characterized by modifying the surface of the formed fine pigment particles within the thin-film fluid (forced thin film).
