Abstract:
A method for stabilizing discharge of dye-based aqueous ink in ink jet recording, comprising the steps of:selecting an ink comprising a dye, water, and an aliphatic or an alicyclic monohydric alcohol for releasing association of water molecules contained in the ink, the aliphatic or alicyclic monohydric alchohol being selected from the group consisting of 1-hexanol, cyclohexanol, and heptanols, and having a vapor pressure of 4 mmHg or less at 25.degree. C.; anddischarging the ink in an amount, corresponding to a single pulse of energy, from 5 to 20 pl/dot, said discharge being stabilized by the aliphatic or alicyclic monohydric alcohol releasing the association of water molecules contained in said ink.
