Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a water-based gravure ink for lamination excellent in adhesiveness, boiling resistance and retorting resistance, and to provide a laminate using the ink. SOLUTION: A first constitution comprises the water-based gravure ink for lamination comprising a pigment, a binder resin and a water-based solvent. The binder resin has a weight average molecular weight of 20-200 thousands, a pH of 6-10 and an acid value of 10-100 mg KOH/g, and includes a urethane resin having polytetramethylene glycol as a polyol component. A second constitution comprises a laminate comprising a substrate film layer, a printed layer using the above ink, an adhesive layer and a sealant layer in this order. COPYRIGHT: (C)2004,JPO&NCIPI
