Abstract:
Provided are: a binder for water-based liquid inks, which is usable in water-based liquid inks excellent in terms of adhesion to substrates, blocking resistance, and ink redissolution; and a water-based liquid ink composition including the binder. This binder for water-based liquid inks comprises: a urethane resin (A) that is a product of the reaction of polyols (a1) comprising an acid-group-containing polyol (a1-1) and a polyether polyol (a1-2) other than the polyol (a1-1) with a polyisocyanate (a2); and an aqueous medium (B). Said binder is characterized in that the urethane resin (A) has an acid group that has been neutralized with a metal salt, and the urethane resin (A) includes an alicyclic structure in an amount in the range of 1,000-5,000 mmol/kg with respect to the entire urethane resin (A).
