PROBLEM TO BE SOLVED: To provide a two-liquid type water-based ink set for inkjet recording, which shows excellent rubbing resistance immediately after printing without causing image disturbance such as bleeding or bleeding between colors even when the ink is printed on a plastic film.SOLUTION: The water-based ink set for inkjet recording comprises a first ink and a second ink. The first ink comprises a coloring material, a resin having a hydroxy group and/or a carboxyl group, and a water-soluble solvent and/or water. The second ink comprises a cationic polyurethane resin (A) having a structural unit expressed by general formula [I], and a water-soluble solvent and/or water. In formula [I], Rrepresents an alkylene chain optionally including an aliphatic cyclic structure, a divalent phenol residue, or a polyoxyalkylene chain; Rand Reach independently represent an alkyl group optionally including an aliphatic cyclic structure; Rrepresents a residue of a quaternarizing agent; and Xrepresents an anionic counter ion. |
