Abstract: An object of the present invention is to provide a method for producing a binder for inks and for use in producing an inkjet printing ink that has both good ink dischargeability and blend stability. A method for producing a binder for inkjet printing inks, the binder containing a hydrophilic-group-containing urethane resin (A), an acetylene compound (B), and an aqueous medium (C), includes step (1) of allowing Ga polyol (a1) containing a hydrophilic-group-containing polyol to react with a polyisocyanate (a2) in an organic solvent or in the absence of a solvent and feeding the organic solvent as needed to prepare an organic solvent solution [I], step (2) of mixing the organic solvent solution [I] with the acetylene compound (B) and the aqueous medium (C) to prepare a mixture [II], and step (3) of removing the organic solvent contained in the mixture [II].
