Abstract
An ink for an ink-jet recording apparatus contains water, a pigment, a resin, 1,3-propanediol, and an organic solvent. The resin has a weight-average molecular weight of 30,000 to 150,000. The content of the resin is 1.5% to 6.0% by mass with respect to the mass of the ink. The total content (P+Q) of the content of the glycerol (P) and the content of the 1,3-propanediol (Q) in the ink is 15% to 40% by mass with respect to the mass of the ink. The mass ratio (P/Q) is 0.25 to 1.00.
