This invention discloses a kind of aqueous dispersion of the nano pigment and its preparation method. The said method is fixing the hydrophobic colorant fully dissolved in polymer monomers into the nano microballoons of the cross linking polymers at the molecule-separate and colorant-aggregative-phase state by using the modified polyreaction in fine latex to obtain the seeds of prepolymerization, then constructing a modified and protective cross linking encloser of the polymer by the enveloping polyreaction, and finally making the nano pigment grains stably disperse in the water medium dissolved with the surface activating agent at a low concentration. The invented aqueous dispersion of the nano pigment is suitable for aqueous ink-jet color marking ink in high performance and color-screened distemper pieces used for making liquid crystal display devices. It can also be applied in pigmentation of the coatings, pigment materials of the high-end cosmetics and so on.

Apparatus and method of making an ink-jet-ink-derived material image on a receiver. An ink jet device is used to form a coagulable ink image on a member, the ink image including a coagulable marking ink and a non-marking ink. Each smallest resolved imaging area of the ink image includes a predetermined mixed volume of the coagulable marking ink and the non-marking ink, the predetermined mixed volume being coagulable. Coagulates are formed within the coagulable ink image, and excess liquid is removed from the coagulates to form an ink-jet-ink-derived material image. The ink-jet-ink-derived image is transferred from the operational surface of the intermediate member to another member, which another member may be a receiver member, a drum or a web.

The invention discloses a method for preparing a nanometer coloring material watercraft dispersoid which is prepared by the miniemulsion polymerization-core shell copolymerization of common dyes or common pigments. The specific steps are that: A. preparing prepolymer seeds; B. preparing shell polymerization emulsion; and C. carrying out core shell polymerization reaction. The average granular size of the dispersoid is less than 100nm, the polydispersity index is less than 0.1 and the granularity uniformity is high; by adopting miniemulsion polymerization-core shell copolymerization for preparation, the method firmly combines pigments or dyes with proper nanometer polymer in a chemical manner, consequently, the dispersoid has excellent storage stability; as organic silicon/acrylic acid polymer are introduced, the dispersoid has fine water resisting property, light resistance, weather resistance and heat resistance. The nanometer coloring material watercraft dispersoid of the invention is applicable for colorized ink jet marking ink, colorized monitors, colored filters, colored coatings, water color ink, watercraft UV color sizing, cosmetics and coloring toner for high-grade products, and the like.

An ink jet device selectively ejects droplets of non-marking liquid ink into cells of a printing member in a desired latent negative image pattern. Certain cells of the printing member are filled with pigmented ink to create a desired image. An electrical bias is applied for fractionating pigment in the pigmented ink from liquid and transferring an image-wise pigmented ink pattern from the printing member to a receiving member, leaving behind a substantial portion of liquid. The receiver can be an intermediate member whereby the image-wise ink pattern is transferred from the intermediate member to a final receiver, while such receiver is in operative association with said intermediate member.

This invention relates to the field of authentication of coating compositions such as varnishes, inks and paints, and it is particularly useful in the field of authentication of such coating compositions when applied to substrates like banknotes or other valuable documents. It is particularly directed to a marked coating composition. e.g. an ink, that is marked with a marker (taggant) such as to allow for its authentication, and a method for authenticating such a marked coating composition. The marking is achieved by covalently binding a taggant to a coating composition component. e.g. such used for security documents. The taggant, which is not extractable through usual chemical treatments like washing methods or the use of solvents, can be detected and identified upon thermally induced chemical fragmentation with a PY-GC-MS apparatus. The marked ink or the marked substrate is thus authenticated as belonging to a particularly marked ink, varnish or batch.
