This disclosure relates to a method of 3-D printing comprising: applying a layer of build material onto a print platform, wherein the build material comprises particles of a polymer comprising polymer chains having at least one reactive group that is protected with a protecting group; printing a de-protecting agent at selected locations on the layer of build material; and coalescing particles of the polymer at the printed locations on the layer of build material to form a coalesced polymer layer.

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.

Polymer compositions suitable for modeling are provided as plastisols with a high content of volatile substances, such as bactericidal, aromatizing, and/or flavoring volatiles. Such plastisols are provided by mixing a lyophilic polyamide or lyophilic complex polyester with a plasticizer of moderate to low polarity that includes a bactericidal, aromatizing, and/or flavoring components, such as an essential oil. After mixing, additives such as fillers, pigments, and gelling agents are added. A solid plastic is producing by heating the formed plastisol to a gelation temperature and then heating to a solution temperature to generate a solid plastic with enduring bactericidal activity, scent, and/or flavor.

There are provided: a microcapsule that includes a shell part containing a polymer and a core part which is encapsulated in the shell part, where the core part contains a coloring material and the polymer has an ultraviolet absorbent skeleton in the main chain thereof; and an application of the microcapsule.
