PROBLEM TO BE SOLVED: To provide an inkjet ink achieving all of ink storage property, picture quality and discharge property by selecting and using a specified combination of a dispersant species to be used and an additive species, particularly an additive species for controlling surface tension, and thereby to solve conventional problems about difficulty in achieving all of ink storage property, picture quality and discharge property.SOLUTION: An inkjet recording ink is provided, comprising at least water, a pigment and an organic solvent, in which the pigment is dispersed by use of a nonionic dispersant. The ink further comprises an anionic surfactant, and a linear block copolymer in which dimethyl polysiloxane and polyalkylene oxide are alternately and repeatedly bonded. |
