1. An inkjet ink comprising:
a water-dispersible colorant; a surfactant; a penetrating agent; a water-dispersible resin; a wetting agent comprising at least polyhydric alcohol having an equilibrium moisture content of 30% by mass or higher at 23° C., 80% RH; a compound of formula (1); water; and at least one selected from the group consisting of a compound of formula (2), a compound of formula (3), and a compound of formula (4), wherein the water-dispersible colorant is at least one selected from the group consisting of a self-dispersible pigment, a pigment dispersed by a pigment dispersing agent, and resin particles each comprising a pigment, wherein a total amount of the water-dispersible colorant and the water-dispersible resin is from 8% by mass to 35% by mass, and wherein a mass ratio of the water-dispersible resin to the water-dispersible colorant is from 2 to 8: wherein R1 is a C4-C6 alkyl group, wherein R2 is a hydrogen atom, a methyl group, or an ethyl group, and R3 is a C1-C4 alkyl group, wherein R4 is either a methyl group or an ethyl group, and R5 is a hydroxyl group, a C1-C8 alkyl group, a cycloalkyl group, or an aryl group, wherein R6 and R7 are each independently a C1-C8 alkyl group. |
