The present invention addresses the problem of providing a laminate having excellent blocking resistance and production efficiency without using a flame lamination method and a base fabric. The present invention provides a laminate which comprises a polyurethane foam and a cured product of a moisture-curable hot-melt polyurethane resin composition, and which does not comprise a base fabric, and which is characterized in that the curing time of the moisture-curable hot-melt polyurethane resin composition is less than 60 seconds. Furthermore, the present invention provides a skin material for a vehicle sheet, which is characterized in that a skin layer is further provided on the polyurethane foam. The moisture-curable hot-melt polyurethane resin composition preferably uses an aromatic polyester polyol as a polyol raw material.
本发明要解决的课题在于提供一种不使用火焰层压法和基布,抗粘连性和生产效率优异的层叠体。本发明提供一种层叠体,其特征在于,其是具有聚氨酯发泡体和湿固化型聚氨酯热熔树脂组合物的固化物且不具有基布的层叠体,所述湿固化型聚氨酯热熔树脂组合物的固化时间小于60秒。另外,本发明提供一种车辆片材用表皮材料,其特征在于,在所述聚氨酯发泡体上进一步设置有表皮层。作为所述湿固化型聚氨酯热熔树脂组合物,优选使用芳香族聚酯多元醇作为多元醇原料。
