Abstract
A polyurethane resin having an anionic group and a polyalkylene oxide in a side chain thereof is obtainable by reacting a polyester polyol, a polyether diol, a polyol containing an anionic group, and a polyisocyanate, and the polyester polyol is obtained by reacting an aromatic polycarboxylic acid and a polyol. The polyurethane resin can be used as binder in an ink jet ink and provides excellent scratch and solvent resistance of printed images.
