Provided are the following: a printing ink in which 95 mass % or more of solvent components are constituted from a single type of alcohol-based solvent and water and the ink exhibits good drying properties, printing stability and physical properties, thereby facilitating during printing the recovery of volatile solvents and a reduction in the number of trapping defects caused by ink permeation; and printed material obtained by printing with this printing ink. The printing ink contains a polyurethane-polyurea resin, a coloring agent and a single type of alcohol-based solvent, wherein the polyurethane-polyurea resin is a resin obtained by reacting, as essential components, a polyurethane prepolymer (X) which is obtained by reacting an alcohol component having a polyoxyalkylene glycol (A) as an essential component with an isocyanate component having a diisocyanate as an essential component, and an amine component (Y) that contains a monoamine (y1) having an alicyclic hydrocarbon group and a diamine (y2). |
