This solvent-curable inkjet ink is characterized by comprising a polyester polyol having a molecular weight of 8000 or less, a hydroxyl value of 17-50 (KOH mg/g), and a glass transition temperature (Tg) of 70 DEG C or lower and a polyisocyanate dissolved or dispersed in a volatile organic solvent. Through use of this ink, an inkjet-printed image that is bonded without smearing can be formed on surfaces of various types of molded articles by heating at low temperature for a short time.
