Zusammenfassung:	To provide a laminated film capable of improving adhesion between an inkjet printing layer and a can body.SOLUTION: There is provided a laminated film 20A in which an overcoat layer 21, a plastic film layer 22, an inkjet primer layer 23, an ultraviolet curable type inkjet printing layer 24, a transparent primer varnish cured layer 25 and an adhesive curing layer 26 are laminated in this order. The transparent primer varnish cured layer 25 contains (1) a polyester-based polyurethane resin, (2) isocyanurate/allophanate mixed type hexamethylene diisocyanate, and (3) a vinyl chloride vinyl acetate copolymer resin.SELECTED DRAWING: Figure 2 【課題】インクジェット印刷層と缶体との密着性を向上することができる積層フィルムを提供する。【解決手段】積層フィルム２０Ａは、オーバーコート層２１、プラスティックフィルム層２２、インクジェットプライマー層２３、紫外線硬化型インクジェット印刷層２４、透明プライマーニス硬化層２５及び接着剤硬化層２６がこの順に積層されている。そして、透明プライマーニス硬化層２５が、（１）ポリエステル系ポリウレタン樹脂と、（２）イソシアヌレート／アロファネート混合型ヘキサメチレンジイソシアネートと、（３）塩化ビニル酢酸ビニル共重合樹脂と、を含有する透明プライマーニス組成物の硬化層である。【選択図】図２
