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.

The present invention relates to a polymeric aromatic amide dispersant, and a composition containing a particulate solid, an aqueous or polar organic medium, and a polymeric aromatic amide dispersant having at least one tertiary amide linking group connecting through a carbonyl group of the amide to an aromatic ring having a residual carboxylic acidic group thereon. The invention further provides compositions for millbases, dispersions, coatings and inks.

A method for preparing a large-area structural chromogenic pattern by ink-jet printing, a structural chromogenic pattern obtained by the method, and an anti-counterfeiting method based on a structural color change. A dispersion liquid containing mono-disperse colloidal microspheres with high index of refraction is printed onto a piece of paper by using an ink-jet printer, and nano-microspheres are arranged and assembled on the paper to obtain a micro-structure having the features of being ordered from a short distance and disordered from a long distance. A pretty structural color can be observed by means of the interaction of the structure with light, thus displaying a pattern, changing the angle of observation, changing the brightness of the structural color, and hiding and displaying the pattern. The method is simple and convenient, is widely applicable, and can achieve the preparation and anti-counterfeiting of a large-area structural color without external stimulation.
