    Abstract: Aqueous dispersion, comprises at least a pigment partially coated with at least radiation-hardenable polyurethane, where the polyurethane is obtained by a reaction of a diisocyanate, a compound with at least two isocyanate functional groups and an oxo compound (I). Aqueous dispersion, comprises at least a pigment partially coated with at least a radiation-hardenable polyurethane, where the polyurethane is obtained by a reaction of a diisocyanate, a compound with at least two isocyanate functional groups and an oxo compound (I) of formula (R2>-CH=C(R1>)-C(=O)-X1>-A1>-X2>) (where the R2>-C bond is a wavy bond). R1>, R2>H or 1-10C alkyl; X1>O or N-R3>; A1>1-20C alkylene (optionally substituted by 1-4C alkyl, O-(1-4C) alkyl or phenyl (where one or more CH2 groups in 1-20C alkylene can be replaced by O); X2>OH or NH-R3>); and R3>H, 1-10C alkyl or phenyl. Independent claims are included for: (1) the preparation of aqueous dispersion; (2) a method for coloring or printing on substrates comprising using the aqueous dispersion; (3) substrates, colored or printed by the above process; (4) a preparation of ink for ink-jet procedure comprising using the aqueous dispersion; (5) an ink for ink-jet printing comprising the aqueous dispersion; (6) a method of printing on substrates comprising using ink by the ink jet printing; (7) printed substrates, obtained by the process; and (8) at least partially coated pigment, manufactured by dispersing at least the pigment and the radiation-hardenable polyurethane.
