Abstract
An ink jet printing ink includes a colorant selected from acid dyes and reactive dyes, an organic solvent, and water. The organic solvent has a solubility parameter value greater than or equal to 11 and less than or equal to 13.5. The organic solvent also has a viscosity, at 20° C., greater than or equal to 10 mPa·s and less than or equal to 180 mPa·s.
