An ink set for inkjet recording comprising:
- a first liquid which contains at least a water-soluble solvent, water, and pigment particles dispersed and retained in a medium including the water-soluble solvent and the water;
- and
- a second liquid which does not contain coloring material but contains at least a water-soluble solvent, water, and a liquid composition which enhances printing characteristics, wherein:
- an image is formed by making the first liquid and the second liquid come into contact with each other on a recording medium;
- and
- a ratio of pigment particles having a particle diameter of not less than 150 nm is not greater than 2 volume percent with respect to a whole of the pigment particles contained in the first liquid.
An image recording method comprising the steps of:
- applying a second liquid of an ink set to a recording medium;
- and
- applying a first liquid of the ink set to the second liquid so that the first liquid and the second liquid come into contact with each other to form an image, wherein the ink set comprises the first liquid which contains at least a water-soluble solvent, water, and pigment particles dispersed and retained in a medium including the water-soluble solvent and the water;
- and the second liquid which does not contain coloring material but contains at least a water-soluble solvent, water, and a liquid composition which enhances printing characteristics, wherein a ratio of pigment particles having a particle diameter of not less than 150 nm is not greater than 2 volume percent with respect to a whole of the pigment particles contained in the first liquid.
