A radiation curable polyurethane resin having an ionic group, a polyalkylene oxide in a side chain thereof and a (meth)acrylate or (meth)acrylamide having a hydroxyl functional group, wherein the polyurethane resin is obtainable by reacting a polyester polyol, a polyether diol, a polyol containing an ionic group, a (meth)acrylate or (meth)acrylamide having a hydroxyl functional group and a polyisocyanate, and wherein the polyester polyol is obtained by reacting a polycarboxylic acid and a polyol. The radiation curable polyurethane resin can be used as binder in an aqueous ink jet ink. 可辐射固化的聚氨酯树脂，其具有离子基团、在其侧链中的聚环氧烷烃以及具有羟基官能团的(甲基)丙烯酸酯或(甲基)丙烯酰胺，其中所述聚氨酯树脂可通过使聚酯多元醇、聚醚二醇、含有离子基团的多元醇、具有羟基官能团的(甲基)丙烯酸酯或(甲基)丙烯酰胺和多异氰酸酯反应而获得，并且其中所述聚酯多元醇通过使多元羧酸和多元醇反应而获得。所述可辐射固化的聚氨酯树脂可以在水性喷墨油墨中用作粘结剂。
