Abstract

An aqueous polyurethane resin dispersion includes a cationic group and a polyalkylene oxide in a side chain thereof. The polyurethane resin is obtainable by reacting a polyester polyol, a polyether diol, a polyol containing a quaternary N-atom or tertiary amino group, and a polyisocyanate. The polyester polyol is obtained by reacting an aromatic polycarboxylic acid and a polyol. The polyurethane resin is suitable as a resin in treatment liquids of substrates and images made by inkjet printing.
