摘要:
It is an object of the present invention to provide a binder for ink-jet printing ink that can form printed images having excellent scratch resistance and good alcohol resistance without impairing good discharge stability of ink. The present invention relates to a binder for ink-jet printing ink including a polyurethane (A) that has a hydroxyl group at a molecular terminal, has a weight-average molecular weight of 30,000 to 70,000, and is obtained by causing a reaction of a polyisocyanate and a polyol (a2) containing a particular polyether polyol so that the equivalent ratio [isocyanate group [X]/hydroxyl group [Y]] of an isocyanate group [X] in the polyisocyanate (a1) to a hydroxyl group [Y] in the polyol (a2) is in the range of 0.930 to 0.995 and an aqueous medium (B). The hydroxyl group present at the molecular terminal of the polyurethane (A) is a hydroxyl group derived from the polyether polyol.
