摘要： A cleaning liquid, usable for cleaning of an ink-jet recording apparatus, includes: a nonionic surfactant, solubility of the nonionic surfactant in water at 20° C. being less than 0.2% by mass; a first water-soluble organic solvent of which solubility parameter is not less than 13; a second water-soluble organic solvent of which solubility parameter is less than 12; and water. The cleaning liquid satisfies the following conditions (1) to (4): X≥0.1; Condition (1): A−B≥0; Condition (2): B/X≥15; Condition (3): 10≤A+B≤60. Condition (4): X: a content amount (% by mass) of the nonionic surfactant, A: a content amount (% by mass) of the first water-soluble organic solvent, and B: a content amount (% by mass) of the second water-soluble organic solvent.

摘要： There is provided a cleaning liquid usable for cleaning of an ink-jet recording apparatus, the cleaning liquid including: a first water-soluble organic solvent, a vapor pressure at 20° C. of the first water-soluble organic solvent being not less than 7 Pa; a second water-soluble organic solvent, a vapor pressure at 20° C. of the second water-soluble organic solvent being not more than 1 Pa; a nonionic surfactant; and water. The cleaning liquid satisfies the following conditions (1) to (3): Condition (1): 10≤A+B≤60; Condition (2): A/B≥1; Condition (3): (A+B)/C≥10. In the conditions (1) to (3), A: a content amount (% by mass) of the first water-soluble organic solvent, B: a content amount (% by mass) of the second water-soluble organic solvent, and C: a content amount (% by mass) of the nonionic surfactant.

摘要： A water-based ink for ink-jet recording includes: a liquid component which is liquid at 20° C.; and a solid component which is solid at 20° C. The liquid component includes: a first water-soluble organic solvent of which vapor pressure at 20° C. is not less than 7 Pa; a second water-soluble organic solvent of which vapor pressure at 20° C. is not more than 1 Pa; and water. The solid component includes at least one resin selected from the group consisting of: acrylic acid-based resin, maleate ester-based resin, vinyl acetate-based resin, carbonate-based resin, styrene-based resin, ethylene-based resin, propylene-based resin, urethane-based resin, vinyl chloride-based resin and copolymer resin thereof.
