Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a moisture-curable hot-melt urethane composition from which an adhesive excellent in initial adhesive strength and releasability can be obtained.SOLUTION: The present invention provides the moisture-curable polyurethane hot-melt resin composition which contains a urethane prepolymer (A) having an isocyanate group, an acrylic polymer (B), a thermoplastic resin (C) having a softening point in the range of 50-80°C, and a curing catalyst (D) represented by general formula (1). The present invention also provides an adhesive obtained by curing the moisture-curable hot-melt urethane composition with moisture.SELECTED DRAWING: None 【課題】本発明が解決しようとする課題は、初期接着強度、及び、剥離性に優れる接着剤が得られる湿気硬化型ホットメルトウレタン組成物を提供することである。【解決手段】本発明は、イソシアネート基を有するウレタンプレポリマー（Ａ）、アクリル重合体（Ｂ）、及び、軟化点が５０〜８０℃の範囲である熱可塑性樹脂（Ｃ）、及び、下記一般式（１）で示される硬化触媒（Ｄ）を含有することを特徴とする湿気硬化型ポリウレタンホットメルト樹脂組成物を提供するものである。また、本発明は、前記湿気硬化型ホットメルトウレタン組成物を湿気硬化させて得られたことを特徴とする接着剤を提供するものである。【選択図】なし
