Abstract

The present application provides a kind of aqueous inkjet ink, even if the printing substrate such as coated paper is difficult to absorb, can obtain the printout without the color mixing bleeding and white leakage caused by droplet aggregation, the droplet dot true circle is excellent, further, printing density and color reproduction are also good, and the stability of jetting is also good.Aqueous inkjet ink, containing: crosslinked polymer particles (A) containing pigment and surfactant (B), crosslinked polymer particles (A) include the crosslinking reaction of compound (A-1) with multiple functional groups reacting with carboxyl and / or carboxylate and non-crosslinked polymer (A-2), surfactant (B) contains polyoxyethylene alkyl ether compound (B-1) with a specific structure and non-ionic surfactant (B-2) with HLB value of 1-10, and the ratio of the content of compound (B-1) to the content of non-ionic surfactant (B-2) is specified.
