Abstract: A water dispersion for inkjet printing, which contains water-insoluble polymer particles containing a colorant. The content of the water-insoluble polymer in the water dispersion is from 1 to 7% by weight, and the surface tension of the water dispersion is 60 mN/m or higher at 20°C. A water-based ink for inkjet printing which contains the water dispersion produces printed images with a high optical density and a good color-to-color bleed resistance.

Abstract: There are provided a water-based ink for ink-jet printing which not only satisfies a high optical density but also is excellent in gloss and image clarity upon printing on a coated paper; a water dispersion used in the water-based ink; and a process for producing the water dispersion. The present invention relates to a water dispersion for ink-jet printing comprising colorant - containing water-insoluble polymer particles which is obtainable by mixing at least two kinds of water-insoluble polymer particles (A) and (B) which are different in average particle size from each other, wherein said polymer particles (A) have an average particle size of 70 to 200 nm and said polymer particles (B) have an average particle size of 15 to 110 nm with the proviso that the average particle size of the polymer particles (A) is larger than that of the polymer particles (B), and a difference between the average particle sizes of the polymer particles (A) and (B) is 10 nm or more; a process for production of the water dispersion; and a water-based ink containing the water dispersion.

Abstract: A water dispersion for inkjet printing which contains polymer particles containing a colorant. The polymer constituting the polymer particles is produced by the copolymerization of a monomer mixture in the presence of a-methylstyrene dimer. The water dispersion for inkjet printing and a water-based ink for inkjet printing containing the water dispersion exhibit excellent jetting properties and a high optical density.
