Abstract:
An ink for inkjet includes water; two or more hydrosoluble organic solvents; a pigment; and a resin particle more than the pigment by weight. A hydrosoluble organic solvent A having the smallest SP value and a hydrosoluble organic solvent B having the largest SP among the two or more hydrosoluble organic solvents satisfy the following relations (1) and (2): SP value of hydrosoluble organic solvent B−SP value of hydrosoluble organic solvent A≧3 (1) boiling point of hydrosoluble organic solvent B>boiling point of hydrosoluble organic solvent A (2).
