Abstract
The ink set for inkjet recording includes: a water-based ink containing pigment particles and 10 to 25 wt % of water-soluble high-boiling-point organic solvent having an SP value of not higher than 30; and a treatment liquid containing a fluidity reducing agent which reduces fluidity of the pigment particles by making contact with the water-based ink, and 10 to 25 wt % of water-soluble high-boiling-point organic solvent having an SP value of not higher than 30.
Claims6
An image recording apparatus which forms an image using the ink set for inkjet recording, comprising an ink set for inkjet recording, comprising:
- a water-based ink containing pigment particles and 10 to 25 wt % of water-soluble organic solvent having an SP value of not higher than 30 (MPa)1/2 and a boiling point of 200° C. or higher at 1 atm;
- and
- a treatment liquid containing a fluidity reducing agent which reduces fluidity of the pigment particles by making contact with the water-based ink, and 10 to 25 wt % of water-soluble organic solvent having an SP value of not higher than 30 (MPa)1/2 and a boiling point of 200° C. or higher at 1 atm,
- wherein the water-based ink and the treatment liquid are substantially free from organic solvent having an SP value of higher then than 30 (MPa)1/2.
