Claim:
A water dispersion for ink jet printing, comprising particles of a water-insoluble crosslinked polymer which contain a colorant, and a water-insoluble organic compound, wherein the water-insoluble crosslinked polymer is produced by crosslinking a water-insoluble polymer with a crosslinking agent; and the water-insoluble organic compound is represented by the following general formula (2): wherein R 1 and R 2 are each independently a hydrogen atom or a hydrocarbon group having 1 to 22 carbon atoms; R 3 is a divalent hydrocarbon group having 1 to 18 carbon atoms; in which R 1 and R 2 may be the same or different with the proviso that both of R 1 and R 2 are not hydrogen atoms at the same time, and R 1 to R 3 optionally having a substituent group selected from the group consisting of a halogen, alkoxy group having 1 to 12 carbon atoms, aryloxy group, oxycarbonyl group, acyl group, acyloxy group, cyano group, nitro group, hydroxyl, carboxyl group, oxo group, epoxy group, ether group and ester group; m and n are each independently an average molar number of addition of AO of 0 to 30; and AO is an alkanediyloxy group.
