Title:
AQUEOUS PIGMENT DISPERSION, AQUEOUS GREEN INK FOR INKJET RECORDING, AND AQUEOUS RED INK FOR INKJET RECORDING
Document Type and Number:
WIPO Patent Application WO/2017/061301
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: an aqueous pigment dispersion which can be used to provide an ink for inkjet recording containing a reduced number of coarse particles and having excellent discharge stability, and which can be applied to a printer equipped with a high-resolution inkjet head; and an aqueous ink for inkjet recording. The present invention pertains to: an aqueous pigment dispersion containing a polymer (A) which has an anionic group, has a water solubility of 0.1 g/100 ml or less, forms fine particles in water when the rate of neutralization of the anionic group by a basic compound is 100%, and has a number-average molecular weight of 1000-6000, a polyhalogenated metal phthalocyanine pigment or a diketopyrrolopyrrole pigment, and water; and an aqueous ink for inkjet recording.
