摘要： An ink comprises a pigment, a quinacridone derivative represented by the following Chemical formula 1. where R1, R2, R3, and R4 each, independently represent hydrogen atoms, halogen atoms, or alkyl groups having 1 to 4 carbon atoms. R5 and R6 each, independently represent alkyl groups having 1 to 4 carbon atoms, and m and n each, independently represent 0, 1, or 2, excluding a case where both m and n are simultaneously 0, and a solvent A having an SP value of from 9.0 to 11.0, wherein the proportion of the solvent A in the ink is less than 10 percent by mass.

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.
