<p>An ink of the present invention includes pigments, dispersed in a resin, a surfactant, a water-soluble organic solvent, and water. In the ink, a weight ratio of the pigments to the resin is greater 3. The surfactant is represented by Chemical formula 1 and includes a fluorine-based surfactant having HLB of smaller than 11 measured by a Griffin method. The water-soluble organic solvent includes one or more selected from a certain group A. In the ink, the total content of the water-soluble organic solvent of the group A is greater than the total content of water-soluble organic solvents except the water-soluble organic solvent of the group A.</p> |
