Zusammenfassung:	To provide a laminate having excellent blocking resistance and production efficiency without using the frame lamination method or base fabric.SOLUTION: A laminate has a polyurethane foam and a cured product of a moisture-curable polyurethane hot-melt resin composition, but does not have base fabric. The moisture-curable polyurethane hot-melt resin composition has a setting time of less than 60 seconds. There is also provided a skin material for vehicular sheets that has the polyurethane foam further having a skin layer thereon. The moisture-curable polyurethane hot-melt resin composition preferably includes, as the polyol material, an aromatic polyester polyol.SELECTED DRAWING: None 【課題】本発明が解決しようとする課題は、フレームラミネート法及び基布を用いず、耐ブロッキング性、及び、生産効率に優れる積層体を提供することである。【解決手段】本発明は、ポリウレタン発泡体、及び、湿気硬化型ポリウレタンホットメルト樹脂組成物の硬化物を有し、基布を有しない積層体であり、前記湿気硬化型ポリウレタンホットメルト樹脂組成物の固化時間が６０秒未満であることを特徴とする積層体を提供するものである。また、本発明は、前記ポリウレタン発泡体の上に、更に表皮層を設けたことを特徴とする車輛シート用表皮材を提供するものである。前記湿気硬化型ポリウレタンホットメルト樹脂組成物としては、ポリオール原料として、芳香族ポリエステルポリオールを用いたものが好ましい。【選択図】なし
