Abstract: Examples of the present disclosure are directed toward an ink composition including a surfactant. An example ink composition consistent with the present disclosure includes a dye colorant dispersion, a solvent, a chelating agent, an oleth-3-phosphate, and a surfactant including a modified fatty alcohol polyglycol ether. In various examples, the dye colorant dispersion is present in an amount ranging from about 1.0 wt % to about 7.0 wt % based on a total weight of the ink, and the solvent is present in an amount ranging from about 10 wt % to about 22 wt % based on the total weight of the ink. The chelating agent may be present in an amount ranging from about 0.05 wt % to about 0.2 wt % based on the total weight of the ink, and the oleth-3-phosphate is in an amount ranging from about 0.1 wt % to about 0.3 wt % based on the total weight of the ink.
