摘要： A water-based ink of the present invention includes water, a plurality of different water-soluble organic solvents, and a water-insoluble coloring material, wherein the water-soluble organic solvents consist of a good solvent to the water-insoluble coloring material and a poor solvent to the water-insoluble coloring material, and the total amount (% by mass) of the good solvents in the ink is represented by A and the total amount (% by mass) of the poor solvent in the ink is represented by B, the ratio of A to B ranges from 10:5 to 10:30 both inclusive, and when the respective Ka values of the above water-soluble organic solvents are determined by the Bristow method and compared with each other, a water-soluble organic solvent having the largest Ka value is the poor solvent. The pigment ink has a sufficiently large area factor even with a small amount of ink.
摘要翻译：本发明的水性油墨包括水，多种不同的水溶性有机溶剂和水不溶性着色材料，其中水溶性有机溶剂由对水不溶性着色材料的良溶剂组成，对水不溶性着色材料的溶剂不良，油墨中的良溶剂的总量（质量％）表示为A，油墨中不良溶剂的总量（质量％）表示为 B，A与B的比例范围为10：5〜10:30，上述水溶性有机溶剂的各自的Ka值均由Bristow法确定并相互比较， Ka值最大的有机溶剂是不良溶剂。即使使用少量的油墨，颜料墨水也具有足够大的面积。
