    • 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.
    • 本发明的目的是提供一种喷墨印刷油墨用粘合剂,其可以形成具有优异的耐擦伤性和良好的耐醇性的印刷图像,而不损害油墨的良好的喷射稳定性。 本发明涉及一种用于喷墨印刷油墨的粘合剂,其包含在分子末端具有羟基的聚氨酯(A),其重均分子量为30,000〜70,000,并且是通过使 多异氰酸酯和含有特定聚醚多元醇的多元醇(a2),使多异氰酸酯(a1)中的异氰酸酯基[X]与羟基[Y]的当量比[异氰酸酯基[X] /羟基[Y] 在多元醇(a2)中的含量在0.930〜0.995的范围内,和水性介质(B)。 存在于聚氨酯(A)的分子末端的羟基是衍生自聚醚多元醇的羟基。
