Aqueous ink composition for ink-jet recording, and image formation method

An aqueous ink composition for ink-jet recording and an image formation method, the aqueous ink composition comprising a colorant, water, organic solvent d-1, which is represented by formula 1 or 2 and has a ClogP value of 0.5-3.5, and resin particles comprising a resin that contains monomer unit c-...

Beschreibung
Zusammenfassung:	An aqueous ink composition for ink-jet recording and an image formation method, the aqueous ink composition comprising a colorant, water, organic solvent d-1, which is represented by formula 1 or 2 and has a ClogP value of 0.5-3.5, and resin particles comprising a resin that contains monomer unit c-1 in an amount of 1-20 mass% with respect to the whole resin, the monomer unit c-1 having a ClogP value larger than that of the organic solvent d-1 and having an anionic group. The content of the organic solvent d-1 is 0.5-10 mass% with respect to the whole aqueous ink composition for ink-jet recording.
