Aqueous dispersion, useful e.g. to prepare coloring composition, comprises a pigment coated with radiation-hardenable polyurethane

摘要

Aqueous dispersion (A) comprises a pigment coated at least partially with a radiation-hardenable polyurethane obtained by reacting a di- or polyisocyanate containing an average of 1-10 allophanate and an average of 1-10 carbon-carbon double bonds per molecule; diisocyanate and a compound with at least two reactable isocyanate groups. Independent claims are included for: (1) the preparation of aqueous dispersion; (2) a substrate, colored or printed by the process; (3) an ink for ink-jet-process containing (A); (4) a process for printing on substrate using ink by the ink jet process; (5) a printed substrates, obtained by the process; (6) a radiation-hardenable polyurethane; and (7) a partially coated pigment, manufactured by dispersing the pigment and the polyurethane.
