Water-based ink for ink-jet recording, water-based ink set for ink-jet recording, ink cartridge, and ink-jet recording method

摘要

A water-based ink for ink-jet recording includes a pigment; water; an acetylene glycol-based surfactant contained by 0.1% by weight to 0.3% by weight in the water-based ink; tripropylene glycol methyl ether contained by 2.5% by weight to 4.5% by weight in the water-based ink; and tripropylene glycol n-butyl ether contained by 0.5% by weight to 1.5% by weight in the water-based ink.

1. A water-based ink for ink-jet recording comprising:
a pigment; water; an acetylene glycol-based surfactant contained by 0.1% by weight to 0.2% by weight in the water-based ink; tripropylene glycol methyl ether contained by 3.5% by weight to 4.5% by weight in the water-based ink; and tripropylene glycol n-butyl ether contained by 0.5% by weight to 1.0% by weight in the water-based ink, wherein:
a weight ratio (a/p) of the acetylene glycol-based surfactant (a) to the pigment (p) is in a range of 0.017/1 to 0.033/1;a weight ratio (b/p) of tripropylene glycol methyl ether (b) to the pigment (p) is in a range of 0.58/1 to 0.75/1; anda weight ratio (c/p) of tripropylene glycol n-butyl ether (c) to the pigment (p) is in a range of 0.083/1 to 0.17/1.
