Abstract
An embodiment relates to an inkjet ink containing a mixed crystal pigment including two or more naphthol-based azo pigments, a binder resin (a-1) having an acid value of 1 to 80 mgKOH/g, a surfactant, and a water-soluble organic solvent, in which the amount of a water-soluble organic solvent having a boiling point of 240° C. or more at 1 atmosphere is 8% by mass or less relative to the total amount of the water-based inkjet ink.

A water-based inkjet ink comprising a colorant, a binder resin (A), a surfactant, and a water-soluble organic solvent, wherein
- the colorant includes a mixed crystal pigment containing two or more naphthol-based azo pigments,
- the binder resin (A) includes a binder resin (a-1) having an acid value of 1 to 80 mgKOH/g,
- the binder resin (a-1) includes a polyolefin resin, and at least one type of resin selected from the group consisting of a (meth)acrylic resin and a styrene-(meth)acrylic resin, and
- an amount of a water-soluble organic solvent having a boiling point of 240° C. or more at 1 atmosphere is 8% by mass or less relative to a total amount of the water-based inkjet ink.
A water-based inkjet ink comprising a colorant, a binder resin (A), a surfactant, and a water-soluble organic solvent, wherein
- the colorant includes a mixed crystal pigment containing two or more naphthol-based azo pigments,
- the two or more naphthol-based azo pigments include 10 to 80% by mole of C.I. Pigment Red 150 in a total amount of the naphthol-based pigments,
- the binder resin (A) includes a binder resin (a-1) having an acid value of 1 to 80 mgKOH/g, and
