摘要： A print method includes applying a first ink to a recording medium to form a first ink print layer, drying the first ink print layer to a drying ratio of 30 percent or less, and applying a second ink having a color different from that of the first ink to the first ink print layer to form a second ink print layer thereon, wherein the first ink includes a urethane resin particle and a water-soluble organic solvent having a boiling point of from 100 to 180 degrees C. or β-alkoxy propionamide of Chemical formula I, where R1 represents a methyl group, an ethyl group, a propyl group, or a butyl group and R2 and R3 each, independently represent alkyl groups having one to six carbon atoms, and the first ink and the second ink includes no organic solvent having a boiling point of 280 degrees C. or higher under 1 atm.

摘要： 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).
