Abstract
Provided are an ink jet recording ink including an organic solvent which is at least one selected from the group consisting of a compound represented by Formula 1 and a compound represented by Formula 2 and has a Clog P value of 1.0 to 3.5, resin particles which contain a resin having 1% by mass to 20% by mass of a structural unit represented by Formula 3 with respect to a total mass of the resin, a silicone-based surfactant, and water, and an image recording method. The description in Formula 1, Formula 2, and Formula 3 has been made in the specification.
Claims6
An ink jet recording ink comprising:
- a pigment;
- a dispersant;
- an organic solvent which is at least one selected from the group consisting of a compound represented by Formula 1 and a compound represented by Formula 2 and has a Clog P value of 1.0 to 3.5;
- resin particles which contain a resin having 1% by mass to 20% by mass of a structural unit represented by Formula 3 with respect to a total mass of the resin;
- a silicone-based surfactant;
- and
- water,
- wherein, in Formula 1 or 2, R1s each independently represent a hydrogen atom or a methyl group, R2s each independently represent a linear or branched hydrocarbon group having 4 to 9 carbon atoms, or an aryl group having 6 to 10 carbon atoms, and n represents an integer of 1 to 3,
- in Formula 3, R3 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms, X1 represents a divalent linking group, Y1 represents an anionic group, and an atom included in X1 or Y1 and farthest from a main chain is separated from the main chain by a distance of 4 atoms to 27 atoms.
