PROBLEM TO BE SOLVED: To provide a solvent curable inkjet ink which can form an inkjet printing image which is adhered on a surface of various kinds of formed parts without running by heating at short time and low temperature.SOLUTION: A polyester polyol and a polyisocyanate having molecular weight equal to or less than 8000, a hydroxyl value (KOHmg/g) of 17-50, and a glass transition point (Tg) equal to or less than 70°C are dissolved or dispersed in a volatile organic solvent. 【課題】低温短時間での加熱により、各種の成形品の表面に滲みなく密着したインクジェット印刷像を形成することが可能な溶剤硬化型インクジェット用インクを提供する。【解決手段】分子量が８０００以下、１７〜５０の水酸基価（ＫＯＨｍｇ／ｇ）、ガラス転移点（Ｔｇ）が７０℃以下のポリエステルポリオール及びポリイソシアネートが揮発性有機溶剤に溶解乃至分散していることを特徴とする。【選択図】なし
