Abstract
This invention provides a water-based ink jet ink and a method to use the ink. The ink yields high-quality and highly-fast images, is stably ejected, is stably printed for a long period of time, and, at the same time, provides easy recovery in maintenance. The water-based ink jet ink has a pigment, 2-10% by mass of an ink soluble resin, 20-45% by mass of a solvent having a surface tension of 25-40 mN/m, and a silicone-type or fluorine-type surfactant. The ink soluble resin contains a carboxyl or sulfonic acid group as an acidic group and has an acid value of 80-300.
Claims8
A method for recording an image on a recording medium made of a textile, the method comprising a step of:
- ejecting a water-based ink-jet ink on the recording medium made of a textile,
- wherein the water-based ink-jet ink comprises:
- water;
- a pigment;
- an ink-soluble resin contained in an amount of from 2 mass % to 10 mass %;
- a water soluble organic solvent contained in an amount of from 20 mass % to less than 45 mass % and having a surface tension of from 25 mN/m to 40 mN/m;
- and
- a surfactant of a silicon surfactant or a fluorochemical surfactant,
- wherein the ink-soluble resin contains a carboxyl group or a sulfo group as an acid group and has an acid value of from 80 to less than 300.
